Inchubo yekucubungula tintfo letiluhlata tepulasitiki ikakhulukati kuncibilika, kugeleta, kanye nekupholisa tinhlayiya tenjoloba tibe yimikhicito lephelile. Kuyinchubo yekushisa bese kuyapholisa. Kuphindze kube yinchubo yekushintja ipulasitiki kusuka etinhlayiyani kuya kumajamo lehlukene. Lokucubungula kutawuchazwa kusuka emibonweni yetigaba letehlukene inqubo.
1.Kuncibilika
I-heater yale divayisi ivumela tinhlayiya tetintfo letiluhlata kutsi tincibilike kancane kancane tibe ngumfutfo wemanti, lokuyintfo lefanele kakhulu kulungiswa kwekushisa kwetintfo letiluhlata letehlukene. Kukhulisa lizinga lekushisa kutawuvama kusheshisa kuhamba kwetintfo letiluhlata, lokungakhulisa kusebenta kahle kepha kungenteka kungacinisekisi umkhicito. Kufanele kube iBhalansi lefanele. Ngekwengeta, umphumela lomuhle kanye netimphawu tekudzabuka lokusetulu kwekushisa kwe PP kutsi kuncono kwenta tintfo letiluhlata tigelete kahle kuya ekufeni ngesikhatsi sekukhicita kwentela kugwema kugcwaliswa lokunganele noma kubuyela emuva. Kugeleta emuva kusho kutsi kugeleta kwetintfo letiluhlata kushesha kunelizinga lekukhipha. Kukhula kwekusebenta kahle kwekugeleta lokusemkhatsini kulingana nekukhula kwe MFR, lokungulenye yetindlela letikhonako tekucubungula, kepha kuphindze kubangele kusabalalisa lokungajwayelekile kwe MFR, lokungaholela ekukhuleni kwekungasimami, lokungenta kutsi kukhule lizinga lesici. Kepha, imikhicito lephelile ye PP akusiyo imikhicito lenekuciniseka lokusetulu kwebukhulu ngenca yekusebenta, ngako umtselela awusiwo lomkhulu.
2. Sikulufu
Liningi lekucubungula kwe PP licondziswa sikulufu kwentela kushayela fluidity, ngako-ke umklamo wesikulufu unelitfonya lelikhulu. Ubukhulu be diameter butsintsa umphumela, kanye ne compression ratio butsintsa linani lekucindzeteleka kanye nemphumela kanye nemphumela wemkhicito lophelile. Loku kuphindze kufake ekhatsi tintfo letehlukahlukene. (Ema-masterbatches embala, tintfo letingetiwe kanye netingucuko) umphumela wekuhlanganisa. Kugeleta kwemphahla leluhlata kuncike kakhulu ku heater, kepha kushisa kwekukhuhlana kwemphahla leluhlata kutawuphindze kukhicite kushisa kwekukhuhlana kwentela kusheshisa kugeleta, ngako-ke silinganiso sekucindzetelwa kwesikulufu sincane futsi kugeleta kuncane, futsi sivinini sekujika kumele sikhuliswe. Lokushisa kwe-frictional kutawuba ngetulu kwaloko kwesikulufu ngesilinganiso lesikhulu sekucindzetela. Ngako-ke, kuvame kutsiwa kute inkhosi ekucubunguleni ipulasitiki, futsi umuntfu locondza kahle kusebenta kwemshini nguye inkhosi. Kushisa kwetintfo letiluhlata akusiko nje kushisa, kepha nekushisa kwekukhuhlana kanye nesikhatsi sekuphefumula. Ngako lena yinkinga lesebentako, futsi lokuhlangenwe nako kusita kucatulula tinkinga tekukhicita kanye nekusebenta kahle. Uma lesikulufu sidzinga kuba nemphumela lomuhle kakhulu wekuhlanganisa, ngalesinye sikhatsi tikulufu letehlukene letinetigaba letimbili noma tikulufu letinemawele takhiwe futsi tinhlobo letehlukene tetikulufu tihlukaniswe tibe tincenye kwentela kufeza imiphumela leyehlukene yekuhlanganisa.
3. Sikhunta noma inhloko yekufa
Kubumba kabusha kwepulasitiki kuncike enhloko yesikhunta noma yekufa. Lomkhicito lobunjwe ngemjovo unetigaba letintsatfu, futsi lesikhunta siyinkimbinkimbi kakhulu. Kumele kucatshangelwe lizinga lekuncipha. Letinye tiyinhloko yekufa kwemkhicito lochubekako losicaba, lomucu, futsi lofana nenyaliti. Uma ngabe bobunjwa lobukhetsekile, Kuhlukaniswa njenge heterogeneous futsi kudzinga kunaka inkinga yekupholisa kanye nekubumba ngekushesha. Liningi lemishini yepulasitiki yakhelwe njengemijovo yekujova, futsi emandla ekukhipha lacondziswa ngulesikulufu atawubangela kucindzeteleka lokukhulu etindzaweni letincane tekutsengisa, kwenta ncono kusebenta kahle kwekukhicita. Uma inhloko yekufa yakhelwe njengendiza, indlela yekusakata tintfo letiluhlata ngekulingana kuyo yonkhe indzawo, umklamo wenhloko yekufa yekulenga kubaluleke kakhulu, futsi litfuba lekucindzetela lelihle kakhulu likhulisa kuniketwa kwetintfo letiluhlata lokuzinzile kwempompi ye-gill yetimfishi.
4. Kupholisa
Ngaphandle kwesango le sprue lelitfulula tintfo letiluhlata, lesikhunta sekujova siphindze sibe nendlela yekupholisa emanti ekupholisa umklamo wetintfo letiluhlata. Lokubunjwa kwe extrusion kuncike emseleni wemanti ekupholisa kule roller kwentela kufeza umphumela wekupholisa, ngaphandle kwemukhwa wemoya, emanti ekupholisa atfululwa ngco esikhwameni sekuphefumula, kanye nendlela yekupholisa lefana nekuphefumula lokunembobo.
5. Kwengeta
Kucubungula kabusha kanye nekwandziswa kwemkhicito lophelile kutawukhulisa umphumela. Sibonelo, libhande lekubopha licondziswa ngema rollers langembili nalangemuva ngesivinini lesehlukile kwenta umphumela wekungeta. Emandla e-tensile encenye yekungeta lecondzile yemkhicito lophelile ayaciniswa futsi akulula kudzabula, kepha kulula kakhulu kudzabula ngendlela levundlile. Kusabalaliswa kwesisindvo se-molecule kuphindze kutsintse umphumela wekungeta ngesikhatsi sekukhicita ngesivinini lesikhulu. Yonkhe imikhicito lekhishiwe kufaka ekhatsi imicu inekwandziswa lokuhlukile. Vacuum kanye nekwakha umfutfo kungaphindze kutsatfwe njengalenye indlela yekwelula.
6. Nciphisa
Noma nguyiphi intfo leluhlata inenkinga yekuncipha. Lokuncipha kubangelwa kukhula kwekushisa kanye nekuncipha lokubandzako kanye nekucindzeteleka kwangekhatsi lokukhicitwa ngesikhatsi sekwakheka kwe crystal. Kukhuluma ngalokwetayelekile, kunwebeka kwekushisa kanye nekuncipha kulula kuncoba. Kungentiwa ngekwelula sikhatsi sekupholisa ekucubunguleni, kanye nekuchubeka nekugcina umfutfo. Le crystalline leluhlata ivame kuba nemehluko lomkhulu wekuncipha kunetintfo letingabonakali, leticishe tibe yinkhulungwane ye PP. Lishumi nesitfupha, kepha i-ABS ingaba tinkhulungwane letine kuphela. Le ngxenye yomehluko inkulu kakhulu. Lencenye kumele incotjwe esikhunjini, noma tintfo letingetiwe letinciphisa kuncipha tivame kufakwa kuncoba inkinga ye LDPE ivame kufakwa kulelipuleti lelikhishiwe kwentela kwenta ncono inkinga yekubeka intsamo.
