Izinto zokuxhuma ucingo zentambo kagesi zifaka kakhuluI-PE (i-polyethylene), i-PP (i-polypropylene) kanye ne-ABS (i-acrylonitrile-butadiene-styrene copolymer).
Lezi zinto ziyahlukahluka ngezakhiwo zazo, ukusetshenziswa kwazo kanye nezici zazo.
1. I-PE (i-polyethylene) :
(1) Izici: I-PE iyi-resin ye-thermoplastic, engeyona enobuthi futhi engenangozi, ukumelana nokushisa okuphansi, izakhiwo ezinhle kakhulu zokuvikela ugesi kanye nezinye izici. Inezici zokulahlekelwa okuphansi kanye namandla aphezulu okuhambisa ugesi, ngakho-ke ivame ukusetshenziswa njengento yokuvikela ugesi yentambo nekhebula elinamandla aphezulu. Ngaphezu kwalokho, izinto ze-PE zinezici ezinhle zikagesi futhi zisetshenziswa kabanzi ezintanjeni ze-coaxial kanye nezintambo ezidinga amandla aphansi entambo.
(2) Ukusetshenziswa: Ngenxa yezakhiwo zayo zikagesi ezinhle kakhulu, i-PE ivame ukusetshenziswa ekufakweni kwentambo noma ikhebula, izinto zokufakwa kwentambo yedatha, njll. I-PE ingathuthukisa futhi ukugcinwa kwayo komlilo ngokufaka izinto zokuvimbela umlilo.
2. I-PP (i-polypropylene):
(1) Izici: Izici ze-PP zifaka phakathi ukunwebeka okuncane, ukungabi nokunwebeka, izinwele ezithambile, ukushesha kombala okuhle kanye nokuthunga okulula. Kodwa-ke, ukudonseka kwayo kuphansi kakhulu. Izinga lokushisa lokusetshenziswa kwe-PP lingu-30℃ ~ 80℃, futhi izici zayo zikagesi zingathuthukiswa ngokufaka igwebu.
(2) Ukusetshenziswa: Izinto ze-PP zilungele zonke izinhlobo zocingo nekhebula, njengentambo kagesi nentambo kagesi, futhi zihlangabezana nezidingo zamandla okuphuka kwe-UL, futhi zingaba ngaphandle kwamalunga.
3. I-ABS (i-acrylonitrile-butadiene-styrene copolymer):
(1) Izici: I-ABS iyisakhiwo sezinto ze-polymer ze-thermoplastic esinamandla aphezulu, ukuqina okuhle kanye nokucutshungulwa okulula. Inezinzuzo ze-acrylonitrile, i-butadiene kanye ne-styrene three monomers, ngakho-ke inokumelana nokugqwala kwamakhemikhali, ukumelana nokushisa, ubulukhuni obuphezulu bendawo kanye nokuqina okuphezulu.
(2) Ukusetshenziswa: I-ABS ivame ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu nokuqina, njengezingxenye zezimoto, izindawo zokuvala zikagesi, njll. Ngokuphathelene nezintambo zikagesi, i-ABS ivame ukusetshenziswa ukukhiqiza ama-insulator nama-housings.
Ngamafuphi, i-PE, i-PP kanye ne-ABS zinezinzuzo zazo kanye nezimo zokusetshenziswa ezintweni zokuxhuma izintambo zezintambo. I-PE isetshenziswa kabanzi ekufakweni kwezintambo kanye nekhebula ngenxa yezakhiwo zayo ezinhle kakhulu zokufakwa kogesi kanye nokumelana nokushisa okuphansi. I-PP ifaneleka ezinhlobonhlobo zezintambo kanye nekhebula ngenxa yobumnene bayo kanye nokushesha kombala okuhle; i-ABS, enamandla aphezulu kanye nokuqina kwayo, isetshenziselwa ukufakelwa ugesi izingxenye zikagesi kanye nezintambo zikagesi ezidinga lezi zici.
Ungazikhetha kanjani izinto ze-PE, PP kanye ne-ABS ezifanele kakhulu ngokwezidingo zokusetshenziswa kwentambo kagesi?
Uma ukhetha izinto ze-PE, PP kanye ne-ABS ezifanele kakhulu, kubalulekile ukucabangela ngokugcwele izidingo zokusetshenziswa kwentambo kagesi.
1. Izinto ze-ABS:
(1) Izakhiwo zemishini: Izinto ze-ABS zinamandla aphezulu kanye nobunzima, futhi zingamelana nomthwalo omkhulu wemishini.
(2) Ukusebenza kahle kokucwebezela kobuso kanye nokusebenza kahle kokucwebezela: Izinto ze-ABS zinokusebenza okuhle kokucwebezela kobuso kanye nokusebenza kahle kokucwebezela, okufanelekela ukukhiqiza izindlu zomugqa wamandla noma izingxenye zepulaki ezinezidingo zokubukeka okuphezulu kanye nokucutshungulwa okuhle.
2. Izinto ze-PP:
(1) Ukumelana nokushisa, ukuzinza kwamakhemikhali kanye nokuvikelwa kwemvelo: Izinto ze-PP zaziwa ngokumelana nokushisa okuhle, ukuzinza kwamakhemikhali kanye nokuvikelwa kwemvelo.
(2) Ukufakwa kogesi: I-PP inokufakwa kogesi okuhle kakhulu, ingasetshenziswa njalo ku-110℃-120℃, ifanele ungqimba lokufakwa kogesi lwangaphakathi lwentambo kagesi noma njengento yokubeka intambo.
(3) Izinkambu Zokusetshenziswa: I-PP isetshenziswa kabanzi ezintweni zasendlini, ezintweni zokupakisha, ifenisha, imikhiqizo yezolimo, imikhiqizo yokwakha kanye neminye imikhakha, okubonisa ukuthi inobubanzi bokusebenza nokuthembeka.
3, izinto ze-PE:
(1) Ukumelana nokugqwala: Ishidi le-PE linokumelana okuhle kakhulu nokugqwala futhi lingahlala lizinzile ezindabeni zamakhemikhali njenge-asidi ne-alkali.
(2) Ukuvikela kanye nokumuncwa kwamanzi aphansi: Ishidi le-PE linokuvikela okuhle kanye nokumuncwa kwamanzi aphansi, okwenza ishidi le-PE lisetshenziswe njalo emikhakheni kagesi neye-elekthronikhi.
(3) Ukuguquguquka nokumelana nomthelela: Ishidi le-PE liphinde libe nokuguquguquka okuhle nokumelana nomthelela, elifanele ukuvikelwa kwangaphandle komugqa kagesi noma njengento yokubeka intambo ukuze ithuthukise ukuqina kwayo nokuphepha kwayo.
Uma ulayini kagesi udinga amandla aphezulu kanye nokucwebezela okuhle kobuso, izinto ze-ABS zingaba yisinqumo esingcono kakhulu;
Uma ulayini kagesi udinga ukumelana nokushisa, ukuqina kwamakhemikhali kanye nokuvikelwa kwemvelo, izinto ze-PP zifaneleka kakhulu;
Uma intambo kagesi idinga ukumelana nokugqwala, ukuvikela kanye nokumuncwa kwamanzi kancane, izinto ze-PE ziyisinqumo esihle kakhulu.
