5 izinto zokusetshenziswa zepulasitiki ezivamile zocingo nekhebula

Nakuba izinhlobo zeucingofuthiikhebulazihlukahlukene, kodwa iningi lesakhiwo semikhiqizo ziyefana, izinto zokusetshenziswa ziyafana ngokuyisisekelo, izinto zokusetshenziswa ezijwayelekile zifaka izinto zokuqhuba, izinto zokuvikela, izinto zokuvikela, izinto zokuvikela, izinto zokugcwalisa, njll., futhi ngokuya ngokuhlukahluka kwazo izakhiwo zingahlukaniswa cishe zibe izigaba ezimbili, izinto zokusetshenziswa zensimbi, njenge-aluminium yethusi, ingxubevange ye-aluminium, nezinto zokusetshenziswa zepulasitiki. I-PVC ejwayelekile, i-PE, i-PP, njll., ilandelwa yizinhlobo ezi-5 zezinto zokusetshenziswa zepulasitiki ezivame ukusetshenziswaucingofuthiikhebula.

1. I-PVC, itis esetshenziswa kakhulu izinto zokusetshenziswa zepulasitiki ocingweni kanye nekhebula, i-PVC ngokuvamile isetshenziselwa ukufakwa kocingo nekhebula kanye nezinto ezivikelayo, lokhu kungenxa yokuthi i-PVC inezinto eziningi zokuzivikela ezinhle ezingaba isivikelo esihle sentambo nentambo yangaphakathi, njenge-PVC akulula ukuyishisa, ukumelana nokuguga, ukumelana nowoyela, ukumelana nokugqwala kwamakhemikhali, ukumelana nomthelela, Lezi zici ziyenza ibe nomphumela omuhle wokuzihlukanisa nokuvikela, ngakho-ke izinto ezijwayelekile zokufakelwa kocingo nekhebula ngokuvamile ziyi-PVC. izinto zokwakha.

2. VULIWE(I-polyethylene), izici zayo ezingokomzimba ziyi-white translucent waxy structure, inokuguquguquka okuhle kakhulu, inganwetshwa ubude obuthile, ilula kunamanzi, ayinabo ubuthi, kodwa uma iqhathaniswa ne-PVC, i-polyethylene inesimo sokushiswa kalula. Ngisho noma ishiya umlilo, izohlala ishisa isimo, i-polyethylene nayo inezinhlobo eziningi ezinwetshiwe, ezihlanganisa i-LDPE, i-MDPE, i-HDPE, i-LDPE ingenye ye-density ephansi kakhulu, eyaziwa ngokuthi i-polyethylene ephansi yokucindezela, inokuguquguquka okuhle kakhulu. I-MDPE i-polyethylene e-medium density, eyaziwa ngokuthi i-polyethylene yengcindezi ephakathi, ukusebenza kanye ne-polyethylene ephezulu kakhulu kuyafana ngokuyisisekelo. I-HDPE yaziwa nangokuthi i-polyethylene yomfutho ophezulu, ukusebenza kwayo okuphelele kuphakeme kakhulu, ikakhulukazi ukumelana nokushisa namandla emishini kokubili kwenziwe kahle. I-Polyethylene inezindawo ezinhle kakhulu zokuvala ugesi futhi isetshenziswa kakhulu ekufakweni kwezintambo zokuxhumana.

3. EVA(i-ethylene - i-vinyl acetate copolymer), i-thermoplastic efana nerabha, ukusebenza kwayo kanye nokuqukethwe kwe-vinyl acetate (VA) kunobudlelwano obuhle, okuncane okuqukethwe kwe-VA kufana ne-polyethylene, okuqukethwe okuphezulu kufana nezici zenjoloba, i-EVA inokunwebeka okuhle nokumelana nezinga lokushisa eliphansi, amakhemikhali. ukumelana. Ngenkathi ixutshwe ne-LDPE, Ingathuthukisa inkinga yokuthi i-LDPE kulula ukuqhekeka, futhi ukumelana komthelela, ukuthamba nobulukhuni, kanye nokunamathela phakathi kwe-conductor kanye nokufakwa kungaxhunyaniswa kahle futhi kuqiniswe.

4. PP(I-polypropylene), iyona ethatha ingxenye encane kunazo zonke phakathi kwamapulasitiki asetshenziswa kakhulu njengamanje, amandla aphezulu emishini, ukumelana nezinga lokushisa eliphansi, ukumelana nokuguga kuphakeme kakhulu, kuhambisana namandla okuqhekeka okuphezulu, izici zokumunca amanzi aphansi, impahla ye-PP ingaba nekhono esikhundleni esiphezulu. izinto zokuvala imvamisa.

5. I-polyester, lolu hlobo lwezinto ezibonakalayo lubonakala ngokumelana okuphezulu kwezinyembezi, ukumelana nokugqoka okuphezulu, ukunwebeka okuphezulu kanye ne-hysteresis ephansi, umkhawulo ongaphezulu wokushisa osebenzayo ungafinyelela ku-1500 degrees Celsius, okungaphezulu kakhulu kunezinye irabha ye-thermoplastic, kodwa futhi inokumelana okuhle kakhulu kawoyela, izici zokumelana ne-solvent.
