Umehluko phakathi kwe-PVC ethambile ne-PVC eqinile

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

1. Amazinga ahlukene okuthamba nokuqina

Umehluko omkhulu usebulukhunini babo obuhlukene. I-PVC eqinile ayinazo izithambisi, inokuguquguquka okuhle, kulula ukuyibumba, futhi ayiqhekeki kalula, ayinabo ubuthi futhi ayingcolisi, inesikhathi eside sokugcina, futhi inentuthuko enhle kanye nenani lokusetshenziswa. I-PVC ethambile, ngakolunye uhlangothi, iqukethe izithambisi ezinobumnene obuhle, kodwa ithambekele ekuqhekekeni nasekubuneni, ngakho-ke ukusebenza kwayo kulinganiselwe.

1. Iububanzi bohlelo lokusebenzazihlukile

Ngenxa yokuguquguquka kwayo okuhle, i-PVC ethambile ivame ukusetshenziselwa ubuso bezindwangu zetafula, phansi, ophahleni, kanye nesikhumba; i-polyvinyl chloride eqinile isetshenziswa kakhulu kumapayipi e-PVC aqinile, izinto zokufaka, kanye namaphrofayili.

3. Iizicizihlukile

Ngokombono wezici, i-PVC ethambile inemigqa emihle yokwelula, inganwetshwa, futhi inokumelana okuhle namazinga okushisa aphezulu naphansi. Ngakho-ke, ingasetshenziswa futhi ukwenza izindwangu zetafula ezisobala. Izinga lokushisa lokusetshenziswa kwe-PVC eqinile ngokuvamile alidluli ama-degrees angu-40, futhi uma izinga lokushisa liphezulu kakhulu, imikhiqizo ye-PVC eqinile ingase yonakale.

4. Iizakhiwozihlukile

Ubuningi be-PVC ethambile bungu-1.16-1.35g/cm³, Izinga lokumuncwa kwamanzi lingu-0.15~0.75%, izinga lokushisa lokuguquka kwengilazi lingu-75~105 ℃, kanti izinga lokuncipha kokubumba lingu-10~50 × 10-³cm/cm. I-PVC eqinile ngokuvamile inobubanzi obungu-40-100mm, izindonga zangaphakathi ezibushelelezi ezinokumelana okuphansi, azinawo usayizi, azinabo ubuthi, azingcolisi, futhi azinawo amandla okugqwala. Izinga lokushisa lokusetshenziswa alidluli ama-degrees angu-40, ngakho-ke liyipayipi lamanzi abandayo. Limelana nokuguga okuhle futhi livimbela ilangabi.
