Inhliziyo yomthelela we-talc powder ku-mortar yokwakha inekhono layo elimangalisayo lokuthuthukisa ukusebenza kahle, okuyisici esibalulekile esithinta ngqo ukulula nokusebenza kahle kwezinqubo zokwakha. Uma zifakwa ezingxubeni ze-mortar, izinhlayiya ezincane kakhulu ze-talc powder, ezivame ukuba nobukhulu obusukela kuma-micrometer angu-1 kuya kwangu-10, zisebenza njengezinto zokugcoba ezincane kakhulu. Lezi zinhlayiya ziyahlangana phakathi kwezinhlayiya ezinkulu zesihlabathi nesamente, kunciphisa ukungqubuzana okwenzeka ngokwemvelo ngesikhathi sokuxuba nokufaka.

Ukuncipha kokungqubuzana kunomthelela omkhulu ezimpahleni ze-rheological ze-mortar. I-mortar exutshwe ne-talc powder ibonisa ukugeleza okuthuthukisiwe, okuvumela ukuthi igeleze kalula ngaphakathi kwefomu noma eduze kwezinto eziqinisayo. Lokhu kugeleza okukhulayo kuzuzisa kakhulu ezimweni zokwakha eziyinkimbinkimbi, njengokuphonswa kwemininingwane yezakhiwo eziyinkimbinkimbi noma ukugcwaliswa kwezikhala ezincane. Ngaphezu kwalokho, i-talc powder ithuthukisa ukwakheka kwe-mortar, okwenza ukuthi ibunjwe futhi ibunjwe ngokunemba okukhulu. Le mpahla ibaluleke kakhulu ekusetshenzisweni lapho kudingeka khona izindawo ezibushelelezi nezihambisanayo, njengokuplasta noma ukufakwa kwezinto zokuhlobisa.

Imiphumela engokoqobo yokuthuthukiswa kokusebenza kahle ifinyelela kude. Izisebenzi zokwakha zithola ukwehla okukhulu emzamweni womzimba odingekayo ukuxuba, ukuthutha, nokusebenzisa udaka. Lokhu akugcini nje ngokuthuthukisa umkhiqizo wazo kodwa futhi kunciphisa nengozi yokulimala okuhlobene nokukhathala. Emaphrojekthini amakhulu okwakha, lapho isikhathi sibaluleke khona, ukusetshenziswa kwe-talc powder kungaholela ekongeni isikhathi esikhulu, kusheshiswe isikhathi sephrojekthi futhi kuncishiswe izindleko zizonke. Isibonelo, kuphrojekthi yokwakha ephakeme, ukusebenza kahle kodaka oluthuthukisiwe nge-talc kungenza inqubo yokubeka izitini ibe lula, okuvumela abakhi ukuba babeke izitini eziningi ngehora ngokunemba okukhulu.

Ukugcinwa kwamanzi kuyisici esibalulekile se-mortar yokwakha, njengoba kuthinta ngqo inqubo yokumanzisa i-samente kanye nokuqina kwesikhathi eside kwezinto. I-Talc powder idlala indima ebalulekile ekukhuliseni ukugcinwa kwamanzi ngokwakha inethiwekhi evikelayo ezungeze ama-molecule amanzi ngaphakathi kwe-mortar matrix. Isakhiwo se-lamellar sezinhlayiya ze-talc sakha isithiyo esinciphisa ukuhwamuka kwamanzi, sivimbele ukoma ngaphambi kwesikhathi futhi siqinisekise ukuthi i-mortar ihlala isebenza isikhathi eside.

Leli fasitela elide lokusebenza linikeza izisebenzi zokwakha ukuguquguquka okukhulu ekusebenzeni kwazo. Zinesikhathi esiningi sokulungisa indawo yezitini noma amathayili, zilungise ukungapheleli, futhi ziqinisekise ukuhambisana okufanele ngaphambi kokuba udaka lubekwe. Ngaphezu kokuthuthukisa ikhwalithi yomsebenzi oqediwe, ukugcina okuqukethwe kwamanzi okuhle ngesikhathi senqubo yokufutha kubalulekile ekuthuthukisweni kwamandla aphelele odaka. Ukufutha usimende kuyindlela eyinkimbinkimbi yokusabela kwamakhemikhali edinga inani elithile lamanzi ukuze kuqhubeke kahle. Amanzi anganele angaholela ekufutheni okungaphelele, okuholela kudaka olubuthakathaka nolunezimbobo olunamandla ancishisiwe okucindezelayo nokuqina.

Izakhiwo zokugcina amanzi ze-talc powder zizuzisa kakhulu ezindaweni ezishisayo nezomile, lapho ukuhwamuka okusheshayo kungaba yinselele enkulu ekusebenzeni kwe-mortar. Ezindaweni ezinjalo, ukusetshenziswa kwe-talc powder kungasiza ekuvimbeleni i-mortar ukuthi yome ngokushesha kakhulu, kuqinisekiswe ukuthi igcina ukusebenza kwayo namandla. Ngaphezu kwalokho, ngokunciphisa ingozi yokomisa ngaphambi kwesikhathi, i-talc powder iyasiza ekunciphiseni ukwenzeka kweziphambeko zobuso, njengokuqhekeka nokukala, okungalimaza ubuhle kanye nobuqotho besakhiwo sokwakhiwa okuqediwe.

Ukuncishiswa kwesamente ngesikhathi senqubo yokomisa kuyinkinga evamile engaba nemiphumela emibi ekuqineni kwesakhiwo nasekubukekeni kwesakhiwo. Njengoba isamente silahlekelwa umswakama, siyancishiswa, futhi uma ukuncishiswa kungalawulwa kahle, kungaholela ekwakhekeni kwemifantu. Le mifantu ayigcini nje ngokunciphisa ukubukeka kwesakhiwo kodwa futhi ihlinzeka ngezindlela zokungena komswakama, okungaholela ezinkingeni ezahlukahlukene, okuhlanganisa ukukhula kwesikhunta, ukugqwala kokuqina, kanye nokuwohloka kwesakhiwo.

Impuphu ye-talc inikeza ikhambi eliphumelelayo enkingeni yokuncipha kwe-mortar. Izinhlayiya zayo ezincane zisebenza njengezigcwalisi, zihlala ezindaweni ezingenalutho kanye nezikhala ngaphakathi kwe-mortar matrix. Ngokugcwalisa lezi zikhala, i-talc powder inciphisa ushintsho lwevolumu oluvela ngesikhathi sokomisa, inciphisa ingozi yokuqhekeka. Isakhiwo se-lamellar sezinhlayiya ze-talc siphinde sibe negalelo ezimpahleni zaso zokulwa nokushwabana, njengoba izendlalelo zingashelelana, zivumelane nokucindezeleka kwangaphakathi okubangelwa yinqubo yokomisa ngaphandle kokulimaza i-mortar matrix.

Ngaphezu kokuvimbela imifantu, ukunciphisa ukushwabana kuthuthukisa nokuzinza kodaka. Lokhu kubaluleke kakhulu ekusetshenzisweni lapho kudingeka khona ukulingana nokuqondaniswa okunembile, njengokufakwa kwezinto ezilungisiwe noma ukufakwa kwamathayela amakhulu. Ngokulondoloza ukuma nobukhulu obuhambisanayo, udaka oluthuthukisiwe nge-talc luqinisekisa isibopho esiphephile nesihlala isikhathi eside phakathi kwezingxenye zesakhiwo, okuthuthukisa ukusebenza kwesakhiwo sonke.

Amandla okubopha phakathi kwe-mortar kanye nezakhiwo, njengezitini, ukhonkolo, noma itshe, kuyisici esibalulekile sokuqina kwesakhiwo. Ukubopha okuqinile kubalulekile ekudluliseni imithwalo ngempumelelo phakathi kwezingxenye nokuqinisekisa ukuthi isakhiwo singamelana namandla omoya, umsebenzi wokuzamazama komhlaba, kanye nokusetshenziswa kwansuku zonke. Impuphu ye-talc ithuthukisa amandla okubopha ngezindlela eziningi, okwenza kube yisithasiselo esiwusizo sokuthuthukisa ukusebenza kwe-mortars enamathelayo.

Enye yezindlela eziyinhloko i-talc powder ethuthukisa ngazo amandla okubopha ukwandisa ukukhiya komshini phakathi kodaka kanye ne-substrate. Izinhlayiya ezincane ze-talc powder zingena ezimbotsheni nasezingalingani zobuso be-substrate, zidale ukuthungwa okuqinile okuthuthukisa ukumelana kokungqubuzana phakathi kwezinto ezimbili. Lokhu kukhiya komshini kusebenza kahle kakhulu ezindaweni ezinezimbobo, njengezitini namabhulokhi ekhonkrithi, lapho izinhlayiya ze-talc zingagcwalisa khona izikhala futhi zidale ukuxhumana okuphephile kakhudlwana.

Ngaphezu kokukhiya ngomshini, i-talc powder ithuthukisa nezakhiwo zokumanzisa ze-mortar. Ngokunciphisa ukucindezelwa kobuso be-mortar, i-talc powder iyivumela ukuthi isakazeke ngokulinganayo futhi ingene ngokujulile ezimbotsheni ze-substrate. Lokhu kuphumela ekuthinteni okuphelele nokusondelene phakathi kwe-mortar ne-substrate, kwakha isibopho samakhemikhali esiqinile. Izakhiwo zokumanzisa ezithuthukisiwe ze-mortar ethuthukisiwe ye-talc zizuzisa kakhulu ekusetshenzisweni lapho kudingeka khona izinga eliphezulu lokunamathela, njengokufakwa kwe-cladding yangaphandle noma ukulungiswa kwezakhiwo zekhonkrithi ezonakele.

Ukuhlanganiswa kokukhiya ngomshini kanye nezakhiwo ezithuthukisiwe zokumanzisa kuholela ekwandeni okukhulu kwamandla ebhondi. Izifundo zibonise ukuthi izimbotshana eziqukethe i-talc powder zingabonisa amandla ebhondi aphezulu afinyelela ku-30% uma kuqhathaniswa nezimbotshana ezivamile. Lokhu kuqina kwebhondi okuthuthukisiwe akugcini nje ngokuthuthukisa ukuzinza kwesakhiwo kodwa futhi kwandisa ukumelana kwaso nezici zemvelo, njengemijikelezo yokuncibilikisa iqhwa kanye nokuhlaselwa ngamakhemikhali. Ngenxa yalokho, izakhiwo ezakhiwe ngodaka oluthuthukisiwe nge-talc zihlala isikhathi eside futhi zidinga ukulungiswa okuncane phakathi nesikhathi sazo sokuphila, zinikeza inani lesikhathi eside kubanikazi bezindawo kanye nabathuthukisi.

Ekuphetheni, i-talc powder iyisithako esisebenziseka kalula futhi esisebenzayo ekuxubeni udaka lokwakha, enikeza izinzuzo eziningi ezithuthukisa ukusebenza, ukuqina, kanye nokukhanga kobuhle bezinto zokwakha. Amandla ayo okuthuthukisa ukusebenza kahle, ukwenza ngcono ukugcinwa kwamanzi, ukunciphisa ukuncishiswa, nokuqinisa isibopho phakathi kodaka kanye nezinto ezisetshenziswayo kuyenza ibe yingxenye ebalulekile emikhubeni yokwakha yesimanje. Njengoba imboni yokwakha iqhubeka nokukhula, ukusetshenziswa kwe-talc powder cishe kuzokwanda, njengoba inikeza ikhambi elihlala njalo nelingabizi kakhulu lokuhlangabezana nezidingo ezikhulayo zezinto zokwakha ezisebenza kahle kakhulu. Kungakhathaliseki ukuthi kumaphrojekthi okuhlala, ezentengiselwano, noma engqalasizinda, i-talc powder izibonakalise iyimpahla eyigugu, inegalelo ekudalweni kwezakhiwo eziqinile, ezihlala isikhathi eside, nezijabulisa ubuhle.
