Umehluko phakathi kwe-PVC ethambile ne-PVC eqinile

I-PVC ingahlukaniswa ngezinto ezimbili: i-PVC eqinile ne-PVC ethambile. Igama lesayensi le-PVC yi-polyvinyl chloride, okuyingxenye eyinhloko yepulasitiki futhi evame ukusetshenziselwa ukwenza imikhiqizo yepulasitiki. Ishibhile futhi isetshenziswa kabanzi. I-PVC eqinile yenza cishe izingxenye ezimbili kwezintathu zemakethe, kuyilapho i-PVC ethambile ithatha ingxenye eyodwa kwezintathu. Ngakho-ke, yimuphi umehluko phakathi kwe-PVC ethambile ne-PVC eqinile?

1. Amazinga ahlukene okuthamba nobulukhuni

Umehluko omkhulu usebukhuni bawo obuhlukene. I-PVC eqinile ayinazo izinto ezithambisayo, inokuguquguquka okuhle, kulula ukwakha, futhi ayishwabanisi kalula, ayinabo ubuthi futhi ayingcolisi, inesikhathi eside sokulondoloza, futhi inokuthuthukiswa okukhulu kanye nenani lesicelo. I-PVC ethambile, ngakolunye uhlangothi, iqukethe izinto ezithambisayo ezinokuthamba okuhle, kodwa ijwayele ukuba brittleness nobunzima bokulondolozwa, ngaleyo ndlela ukusebenza kwayo kunomkhawulo.

1. Iamabanga wohlelo lokusebenzazihlukile

Ngenxa yokuguquguquka kwayo okuhle, i-PVC ethambile ngokuvamile isetshenziselwa ubuso bendwangu yetafula, phansi, uphahla, kanye nesikhumba; I-polyvinyl chloride eqinile isetshenziswa kakhulu kumapayipi aqinile e-PVC, okokufakwayo, namaphrofayili.

3. Iizicizihlukile

Ngokombono wezimpawu, i-PVC ethambile inemigqa emihle yokwelula, inganwetshwa, futhi inokumelana okuhle nokushisa okuphezulu nokuphansi. Ngakho-ke, ingasetshenziswa futhi ukwenza izindwangu zetafula ezikhanyayo. Izinga lokushisa lokusebenzisa le-PVC eliqinile ngokuvamile alidluli ama-degree angu-40, futhi uma izinga lokushisa liphezulu kakhulu, imikhiqizo ye-PVC eqinile ingase yonakaliswe.

4. Iizakhiwozihlukile

Ukuminyana kwe-PVC ethambile kungu-1.16-1.35g/cm ³, Izinga lokumuncwa kwamanzi ngu-0.15~0.75%, izinga lokushisa lengilazi liyi-75~105 ℃, futhi izinga lokuncipha lokubumba lingu-10~50 × 10- ³cm/cm. I-PVC eqinile ivamise ukuba nobubanzi obungu-40-100mm, izindonga zangaphakathi ezibushelelezi ezinokumelana okuphansi, azinasikali, ezingenabuthi, ezingenakungcola, kanye nezakhiwo ezimelana nokugqwala. Izinga lokushisa lokusetshenziswa alikho ngaphezu kwama-degree angu-40, ngakho-ke ipayipi lamanzi abandayo. Ukumelana nokuguga okuhle kanye ne-flame retardant.
