Gisesengura ibyiza nibibi byinganda zinganda za polyurethane

Icyuma cya polyurethane caster ni ubwoko bwa caster ifite ibikoresho bya polyurethane, bihujwe no gutera ibyuma, ibyuma byuma cyangwa ibyuma bya plaque, bituje, uburemere buke nubukungu, kandi birakwiriye mubidukikije byinshi.
Mubisanzwe, ubunini bwinganda ziri hagati ya santimetero 4 ~ 8 (100-200mm), hamwe niziga rya polyurethane nibyiza. Inziga za polyurethane zifite imbaraga zo kurwanya abrasion, uburyo butandukanye bwo guhindura imikorere, uburyo butandukanye bwo gutunganya, gukoreshwa kwinshi, no kurwanya neza amavuta, ozone, gusaza, imirasire, ubushyuhe buke, nibindi, amajwi meza, imbaraga zifatika, biocompatibilité nziza kandi guhuza amaraso.

Amashanyarazi ya polyurethane arangwa cyane cyane nibi bikurikira:
1. Urwego runini rushobora guhinduka. Binyuze mu guhitamo ibikoresho fatizo no guhindura formulaire, birashobora guhinduka mugihe runaka cyimpinduka mubipimo byerekana imikorere yumubiri nubukanishi, kugirango byuzuze ibisabwa byihariye byumukoresha kumikorere yibicuruzwa. Kurugero, polyurethane elastomers irashobora gukorwa muburyo bworoshye bwo gucapa reberi hamwe nicyuma gikomeye kugirango uhuze ibyifuzo byabakoresha batandukanye.
2. Kurwanya abrasion birenze. Imbere y'amazi, amavuta hamwe nibindi bitangazamakuru byogukora, akazi ko kwihanganira imyuka ya polyurethane ni inshuro nyinshi kugeza ku nshuro icumi ibikoresho bisanzwe bya reberi.

3. Uburyo butandukanye bwo gutunganya nuburyo bukoreshwa. Polyurethane elastomer irashobora kubumbabumbwa muguhindura plastike, kuvanga no gutunga ibirunga (bivuga MPU); irashobora kandi gukorwa mubibabi byamazi, guteramo cyangwa gutera, kubumba no gushushanya (bivuga CPU); irashobora kandi gukorwa mubintu bya granulaire hanyuma ikabumbabumbwa no guterwa inshinge, gusohora, kalendari, guhumeka hamwe nibindi bikorwa (bivuga CPU).
4. Kurwanya amavuta, ozone, gusaza, imirasire, ubushyuhe buke, kwanduza amajwi meza, imbaraga zifatika, biocompatibilité nziza kandi ihuza amaraso.

Nyamara, elastomers ya polyurethane ifite ibibi bimwe na bimwe, nkubushyuhe bukabije bwa endogenous, ubushyuhe bwo hejuru muri rusange, cyane cyane kurwanya ububi nubushyuhe, ntibishobora kwihanganira imishwarara ikomeye ya polar hamwe na aside ikomeye hamwe nigitangazamakuru cya alkali.
