Ukuqina kuyimfuneko ebalulekile emikhiqizweni eminingi yepulasitiki, kusukela kuma-bumper ezimoto kuya ezitsheni zokugcina. I-plastic filler talc powder yethu, enesakhiwo sayo esiyingqayizivele sekristalu ye-lamellar, ikhulisa i-flexural modulus (isilinganiso sokuqina) ngo-30-50% uma ingezwa kuma-resin e-PP. Lokhu kuthuthukiswa kungenxa yendlela izinhlayiya ezisicaba, ezifana nepuleti ze-talc interlock ngaphakathi kwe-matrix yepulasitiki, okudala inethiwekhi yokuqinisa. Isibonelo, umkhiqizi wezingxenye zezimoto ohamba phambili okhiqiza ama-PP bumpers wakwazi ukunciphisa ubukhulu bodonga lwemikhiqizo yawo ngo-18% ngemuva kokufaka i-talc powder yethu. Lokhu akuholelanga nje kuphela ekongeni isisindo okukhulu kodwa futhi kwanciphisa ukusetshenziswa kwe-resin, ekugcineni kunciphisa izindleko zokukhiqiza ngeyunithi ngayinye. Ngaphezu kwalokho, ukuqina okwandisiwe kuqinisekisa ukuthi izingxenye zingamelana nobunzima bokuthutha nokufaka ngaphandle kokugoba noma ukuqhekeka.

Ukuzinza kobukhulu kungenye inzuzo ebalulekile ehlukanisa i-talc powder yethu. Izingxenye zepulasitiki zivame ukubhekana nezinkinga zokushwabana noma zokusonta ngesikhathi senqubo yokupholisa ngemva kokubumba, okungabangela izinkinga zokulingana ezibizayo kanye nokwenqatshwa komkhiqizo. I-talc powder yethu, enobukhulu bayo bezinhlayiya ezilawulwa kahle kanye nokusatshalaliswa kwayo, inciphisa ukushwabana ngo-15-20%. Lokhu kubaluleke kakhulu ezingxenyeni ezinembile njengezixhumi zikagesi, lapho ngisho nokwehluka okuncane kobukhulu kungenza yonke inhlangano ingasebenzi. Inkampani eyaziwayo ye-elekthronikhi ekhiqiza izihlanganisi zamapayipi e-PVC zamapayipi kagesi ibike ukwehla okuphawulekayo okungu-90% kwamazinga okwenqatshwa ngemva kokushintshela ku-talc powder yethu. Ubukhulu obuqhubekayo kuzo zonke izinhlobo zokukhiqiza buqinisekisile ukuthi imikhiqizo yabo ihlangabezana nezindinganiso eziqinile zemboni, okuthuthukisa idumela labo lekhwalithi.

Ngokuphambene nezinye izigcwalisi ezibeka engcupheni ukumelana nomthelela, i-plastic filler talc powder yethu empeleni igcina noma ithuthukisa le mpahla uma isetshenziswa ngezilinganiso ezifanele (10-30% ngesisindo). Lokhu kubaluleke kakhulu emikhiqizweni ethinteka njalo, njengamaphaneli angaphakathi ezimoto noma amathoyizi ezingane. Ukusatshalaliswa kosayizi wezinhlayiya ezifanayo ze-talc powder yethu kuqinisekisa ukusabalala ngisho nokuncibilika kwepulasitiki, okuvimbela ngempumelelo ukwakheka kwamaphuzu okugxila kokucindezeleka angaholela ekuqhekekeni. Umhlinzeki wezingxenye zezimoto waseNyakatho Melika, isibonelo, uthole ukuthi ukufaka i-talc powder yethu kumaphaneli omnyango we-PP kwandisa ukumelana nomthelela ngo-22%. Lokhu kuthuthukiswa kwabasiza ukuthi bahlangabezane nezindinganiso zokuphepha eziqinile ezibekwe abakhiqizi bemishini yokuqala abakhulu (ama-OEM), okubanikeza ithuba lokuncintisana emakethe.

Ukusebenza kahle kwezindleko kuyimbangela enkulu yabakhiqizi bepulasitiki, futhi i-talc powder yethu inikeza ukonga okukhulu. Ngokushintsha i-resin engu-10-30% nge-talc powder yethu eshibhile, abakhiqizi banganciphisa izindleko zezinto zokusetshenziswa ngo-8-15%. Ukuze kuboniswe ukonga okungenzeka, cabanga ngenkampani ekhiqiza amathani angu-5,000 emikhiqizo ye-PP minyaka yonke. Ngokusebenzisa i-talc powder yethu, bangonga imali engaphezu kuka-$200,000 njalo ngonyaka. Ngaphezu kokonga izindleko ngqo kokushintsha i-resin, i-talc powder yethu ithuthukisa nokugeleza kokuncibilika kwepulasitiki. Lokhu kugeleza okuthuthukisiwe kunciphisa ukusetshenziswa kwamandla ngesikhathi sezinqubo zokukhipha kanye nokubumba umjovo, kunciphisa izindleko zokukhiqiza. Kuphinde kuvumele izikhathi zomjikelezo ezisheshayo, kwandise ukuphuma kwamandla futhi kuvumela abakhiqizi ukuthi bahlangabezane nesidingo esikhulu ngaphandle kwesidingo sokuthuthukiswa kwemishini ebizayo.

Inqubo yethu yokukhiqiza iwubufakazi bokuzibophezela kwethu ekhwalithini. Sithola i-talc eluhlaza kusuka ezidiphozithini ezidumile ngokuqukethwe kwayo okuphezulu kwe-magnesium silicate (≥95%) kanye namazinga aphansi okungcola. Inqubo yokukhipha iqala ngokumba ngokucophelela ukuqinisekisa ubuqotho be-ore. Uma isimbiwe, i-talc idlula ochungechungeni lwezinyathelo zokucubungula ngokucophelela. Okokuqala, iyachotshozwa bese igaywa ukuze kuncishiswe usayizi wayo. Ngemuva kwalokho, kusetshenziswa amasu okuhlanza athuthukile, okuhlanganisa ukuhlukaniswa kwamagnetic ukususa izinhlayiya zensimbi kanye nokuntanta kwe-froth ukuze kususwe amaminerali angewona ama-talc. Kuma-grade ethu amahle kakhulu, sisebenzisa ama-jet mill asezingeni eliphezulu anikeza ukulawula okunembile kosayizi wezinhlayiya. Iqoqo ngalinye le-talc powder lihlolwa ngokuqinile ukusatshalaliswa kosayizi wezinhlayiya, ubumhlophe, kanye nokwakheka kwamakhemikhali. Imiphumela yokuhlola enemininingwane ibhalwe ku-Certificate of Analysis (COA) enikezwa amakhasimende ethu, ebanika ukucaca okuphelele kanye nokuzethemba ngekhwalithi yemikhiqizo yethu.

Siyaqonda ukuthi yonke i-plastic application inezidingo ezihlukile, yingakho sinikeza izixazululo ezenziwe ngokwezifiso. Ngemikhiqizo enezindonga ezincane njengefilimu zokupakisha, lapho ukucaca kubalulekile khona, sinikeza i-talc powder engu-2000-mesh. Le powder yezinga elihle isakazeka kalula ngaphakathi kwe-matrix yepulasitiki, iqinisekisa ukuthi ayiphazamisi ukucaca noma izakhiwo ezibonakalayo zefilimu. Ngakolunye uhlangothi, ngezinhlelo zokusebenza ezishisa kakhulu njengezingxenye zezimoto ezingaphansi kwe-hood, ezivezwa ekushiseni okukhulu, sinikeza i-talc ezinzile ekushiseni. Lo mkhiqizo okhethekile wenzelwe ukugcina ukusebenza kwawo ngisho nasemazingeni okushisa afinyelela ku-180°C, ukuqinisekisa ukuthembeka nokuphila isikhathi eside kwezingxenye. Ithimba lethu lobuchwepheshe elizinikele lisebenzisana eduze namakhasimende, lenza izivivinyo ezijulile zokuhambisana nama-resin ahlukene kanye nezithasiselo. Ngalezi zivivinyo, sinquma umthamo ofanele kanye nosayizi wezinhlayiya zesicelo ngasinye, sinikeza izixazululo ezenzelwe wena ezihlangabezana nezidingo ezithile zamakhasimende ethu.

Ukuthunyelwa kwempahla kanye nokusekelwa kwamakhasimende kuyizingxenye ezibalulekile zesevisi yethu. Sinikeza izinketho zokuthumela eziguquguqukayo ngolwandle, emoyeni, noma emhlabeni, okusivumela ukuthi sihlangabezane nezikhathi ezahlukahlukene nezidingo zamakhasimende ethu. Kungakhathaliseki ukuthi kuyi-oda elincane, eliphuthumayo elidinga ukulethwa ngokushesha ngendiza noma ukuthunyelwa okukhulu okungathuthwa ngendlela engabizi kakhulu ngolwandle, sinamakhono okuqinisekisa ukulethwa ngesikhathi. Ukuzibophezela kwethu ekwanelisekeni kwamakhasimende kudlulela ngale kokuthengisa. Ithimba lethu lokusekela ngemuva kokuthengisa lihlala lilindile ukuhlinzeka ngosizo lokuxazulula izinkinga kanye neseluleko sokwenza ngcono ukusebenza. Siyaqonda ukuthi izinkinga zingase ziphakame ngesikhathi sokuhlanganiswa kwe-talc powder yethu enkambisweni yokukhiqiza, futhi sizinikele ekusizeni amakhasimende ethu ukuba anqobe noma yiziphi izinselelo angabhekana nazo. Ngaphezu kwalokho, sinikeza inani lamasampula e-talc powder yethu, okwenza amakhasimende akwazi ukuhlola kahle ukusebenza kwayo ezindaweni zawo ngaphambi kokuzibophezela kuma-oda amakhulu. Le nqubo yokusampula engenazingozi inikeza amakhasimende ethu ithuba lokwenza izinqumo ezinolwazi futhi iqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zayo eziqinile.

Ngenxa yekhono layo lokuthuthukisa ukusebenza nokunciphisa izindleko, i-plastic filler talc powder yethu ithole ukuthandwa kabanzi phakathi kwabakhiqizi eYurophu, e-Asia naseNyakatho Melika. Sekuyisinqumo esithembekile sezinkampani ezifuna ukuthuthukisa ikhwalithi yemikhiqizo yazo ngenkathi zigcina ukuncintisana emakethe yomhlaba wonke. Njengoba isidingo sepulasitiki esebenza kahle siqhubeka nokukhula, i-talc powder yethu izohlala iyisisombululo esiguquguqukayo nesithembekile, esiza izinkampani zepulasitiki ukuthi zihlale phambili embonini eshintsha ngokushesha.
