Nigute wagabanya umunuko wibikinisho bya TPR?

Ibikinisho bya Thermoplastique elastomer TPE / TPR, ishingiye kuri SEBS na SBS, ni ubwoko bwa polymer alloy ibikoresho bifite ibikoresho rusange byo gutunganya plastiki ariko biranga reberi.Buhoro buhoro basimbuye plastiki gakondo kandi nibikoresho byatoranijwe kubicuruzwa byabashinwa kujya mumahanga no kohereza muburayi, Amerika, Ositaraliya, Ubuyapani nahandi.Ifite ubwitonzi bwiza, guhinduranya amabara no gukomera, kurengera ibidukikije, nta halogene, idafite uburozi kandi butaryoshye;Kurwanya kunyerera no kwambara, kurwanya umunaniro ufite imbaraga, kwinjiza neza, guhungabana neza kwa UV, kurwanya ozone no kurwanya imiti;Mugihe cyo gutunganya, ntabwo ikeneye gukama kandi irashobora gukoreshwa.Irashobora gushirwaho muburyo bwa kabiri bwo guterwa inshinge, igasizwe kandi igahuzwa na PP, PE, PS,ABS, PC, PA nibindi bikoresho bya matrix, cyangwa byakozwe bitandukanye.Simbuza PVC yoroshye hamwe na reberi ya silicone.

Impumuro itangwa nibikinisho bya TPR biterwa nimpamvu nyinshi, zirimo imashini, intambwe zo gukora, nuburyo bwo gukora.Ntabwo byanze bikunze TPR izaba ifite umunuko, ariko dushobora kugabanya umunuko kugirango abantu batazumva nabi, kugirango buriwese abyemere.Ababikora batandukanye bafite formulaire zabo, kandi impumuro yakozwe nayo iratandukanye.Kugirango ugere kumunuko woroshye, bisaba guhuza neza formulaire hamwe nibikorwa kugirango bigire imikorere myiza.

1. Inzira

Ibyinshi mu bikinisho bikozwe mubikoresho bya TPR hamwe na SBS nkibikoresho nyamukuru.SBS igomba kwitabwaho muguhitamo.SBS ubwayo ifite impumuro kandi impumuro ya kole yamavuta nini kuruta iyo kole yumye.Gerageza gukoresha K glue kugirango utezimbere ubukana, gabanya ingano ya PS, hanyuma uhitemo amavuta hamwe na flash point yo hejuru yibishashara bya paraffin.Amavuta yera atanduye nayo azagira impumuro runaka nyuma yo gushyuha, birasabwa rero guhitamo ibicuruzwa mubakora bisanzwe.

2. Inzira

Ibicuruzwa bya TPR hamwe na SBS nkibisobanuro nyamukuru bigomba kugenzura neza inzira.Nibyiza kudakoresha umuvuduko mwinshi wo kuvanga ingoma nizitambitse kugirango uvange ibikoresho, kandi igihe ntigikwiye kuba kirekire.Muri rusange, ubushyuhe bwo gutunganya bugomba kugenzurwa nkibishoboka.180 ℃ mugice cyogosha na 160 ℃ mubice bikurikira birahagije.Mubisanzwe, SBS iri hejuru ya 200 ℃ ikunda gusaza, kandi impumuro izaba mbi cyane.Ibice bya TPR byateguwe bigomba gukonjeshwa vuba bishoboka kugirango uhindure umunuko, kandi urebe ko nta bushyuhe bwinshi mugihe cyo gupakira.

3. Gutunganya nyuma

Ibikinisho bimaze gukonjeshwa no guterwa inshinge za TPR, ntugahite ubipakira.Turashobora kureka ibicuruzwa bigahinduka mukirere mugihe cyiminsi 2.Mubyongeyeho, essence irashobora kandi kongerwaho mugihe cyo guterwa inshinge kugirango utwikire uburyohe bwa TPR ubwayo.
