Kunezinhlobo eziningi zemikhiqizo yegwebu le-PVC, ikakhulukazi ehlanganisa izinto zegwebu eliqinile nezinto ezithambile zegwebu (njengezinto zodwa, isikhumba sokwenziwa, njll.). Ipulasitiki ye-Microporous iwuhlobo lwegwebu elinobubanzi obungu-1 ~ 10 μ M, ukuminyana kwegwebu le-1X109 ~ 1×1012 / cm3 impahla entsha yegwebu. Uma kuqhathaniswa namapulasitiki angenagwebu, ukuminyana kwamapulasitiki amancane kungancishiswa ngo-5% ~ 95%. Ngemuva kwe-microcellular foaming, i-PVC ayikwazi nje ukunciphisa ukuminyana futhi yonge izindleko, kodwa futhi ibe nezakhiwo eziningi ezinhle kakhulu zomzimba nezomshini, njengesisindo esilula, amandla omthelela aphezulu, ukuqina okuphezulu, ukufakwa kahle kokushisa nokusebenza kokufakwa komsindo, ukuqhutshwa kwe-conductivity okuphansi kanye ne-thermal conductivity, ukubukeka okuhle, ukumelana ne-asidi ne-alkali, umswakama-ubufakazi kanye nokunqanda ukubola, i-flame retardant futhi ingashi, usayizi ozinzile, ukubumba okulula, umbala ongaphezulu, ukuphrinta noma ukugqoka, ukucubungula okulula Ukumelana nesimo sezulu esihle (kungasetshenziswa ngaphandle) nokunye ukusebenza okuphezulu.

wax we- le-PVC

Izinto eziqinile ze-PVC ezinegwebu ezincane zinezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa amabhodi anegwebu (njengamabhodi ezinyawo anegwebu, imicu yodonga enegwebu, amaphaneli odonga nosilingi, amathayela anombala ophahleni, njll.), amapayipi anegwebu (njengamapayipi okuvikela ikhebula, amapayipi amanzi wemigwaqo nojantshi, amapayipi okwakha indle, amapayipi okunisela ezolimo, amapayipi okuvikela izimboni, njll.), amaphrofayli anegwebu (njengamakhethini amakhethini, amaphrofayili ohlaka lwe-shutter, amaphrofayili eminyango namafasitela Iphrofayili yephaneli ye-balcony, iphansi elingaphakathi nangaphandle, njll.) .

① Ukucweba kwamahhala kubhekisela ekunwetshweni kwamahhala okungakhawulelwe kokuncibilika ngokushesha nje lapho kushiya inhlabathi, bese kungena kudivayisi yokusetha ngosayizi omkhulu ngemva kwesikhathi esifushane. Ukukhihliza amagwebu kwamahhala kwenza wonke amabhamuza akhe esigabeni esiphambanayo se-extrudate. Ukukhula kwamabhamuza angaphezulu kunqunyelwe ukupholisa, futhi ekugcineni kwakheka ukuminyana okuqhubekayo, ubulukhuni obuphakathi nendawo kanye nomkhiqizo obushelelezi. Le ndlela inezinzuzo zenqubo elula futhi ilungele ukukhiqiza imikhiqizo enogqinsi oluyi-2 ~ 6mm, ijometri elula kanye nendawo ebuthuntu (njengamapayipi, amashidi namaphrofayili anejiyomethri elula).
② Indlela yokukhipha amagwebu yangaphakathi, indlela yokukhipha amagwebu esikhumbeni noma indlela ye-celuka isebenzisa ifa elikhethekile elinomongo ngaphakathi ukuze lihlukanise izinto ezenziwe ngepulasitiki, isisetshenziswa sokusetha sixhunywe nedayizi, kanti i-contour yayo yangaphandle iyafana neyokufa. Lapho impahla ithunyelwa kumkhono wokusetha phambi kwendawo yokungena, inyibiliko equkethe igwebu ingena kumkhono wokupholisa ngokushesha nje lapho ishiya ifilimu yomlomo, futhi ipholise ngokushesha yonke indawo, ukuze ivimbele ukwakheka. amabhamuza angaphezulu kanye nanoma yikuphi ukuvuvukala engxenyeni ye-extrudate, ukuze kwakheke ungqimba lwesikhumba ebusweni. Ngesikhathi esifanayo, umgogodla ku-die wenza i-cavity eyakhiwe kumkhiqizo ophelile ogcwele i-foam eyakhiwe ukuncibilika okusele, okungukuthi, ukugwedla ngaphakathi. Ngokulawula amandla okupholisa, imikhiqizo enogqinsi olungaphezulu kuka-0.1 ~ 10mm nogqinsi lodonga lomkhiqizo olungaphezu kuka-6mm. Le ndlela ingakhiqiza amaphrofayili anomumo oyinkimbinkimbi we-cross-section. Imikhiqizo inezici zobuso obushelelezi, ubulukhuni obuphezulu kanye nokuminyana okuphansi endaweni ewumgogodla. Ngaphezu kwalokho, ngokuhlanganisa le ndlela nendlela ①, umkhiqizo onesikhumba ohlangothini olulodwa kanye nesimo esikhululekile ngakolunye uhlangothi ungatholakala.

③ I-Coextrusion isebenzisa ikhanda elihlanganisiwe nama-extruder amabili ukuze ikhiphe isendlalelo sendawo engakhihlizi amagwebu kanye nongqimba oluwumgogodla olunamagwebu ngokulandelanayo. Izinhlobonhlobo noma ifomula yezingxenye ezimbili zamapulasitiki zingalungiswa ngokuvumelana nezidingo zokwenza imikhiqizo ihlangabezane nokuminyana nosayizi odingekayo ngokwezinga. Iningi lamapayipi e-foam ayisisekelo akhiqizwa eChina akhiqizwa yile nqubo.
Nakuba izindlela zokucubungula ezintathu ezingenhla zinezici zazo ekubunjweni kwefomula, ukwakheka kwefa kanye nobuchwepheshe bokucubungula, indlela yokulawula ukuziphatha okunegwebu kokuncibilika nokuthola isakhiwo seseli esanelisayo kuyinkinga evamile eyinhloko enqubweni yokukhipha. Inqubo yokugcina yogwebu yegesi encibilikisiwe empeleni kwenzeka "ngokungazelelwe" ngemva kokuba ukuncibilika kushiya ukufa. Ngemuva kokuthi ukuncibilika kushiya inhlabathi, ngenxa yokwehla okungazelelwe kwengcindezi yendawo kanye nokushintsha kwezinga lokushisa, igesi encibilikisiwe isesimweni esigcwele kakhulu, ukuhlukaniswa kwezigaba ezimbili zegesi-uketshezi, kanye nenani elikhulu lama-microbubbles akhiwa ku-nucleation. iphuzu. Usayizi wokukhula kwebhamuza uncike ekucindezelweni komhwamuko ogcwele wegesi yokubola kanye ne-ductility namandla okuncibilika ngokwawo. Ngakolunye uhlangothi, ngaphansi kwesenzo sokucindezela kwegesi, ama-bubbles akhula ngokuqhubekayo; Ngakolunye uhlangothi, amandla kanye ne-ductility yokuncibilika kuzokhawulela ukukhula kwamabhamuza futhi kunqume ukuthi amabhamuza ayaphuka noma ahlangane. Uma amandla okwandisa angaphandle egesi elinganiswe namandla e-viscoelastic anda ngokuncibilika ngenxa yokupholisa, kufanele apholiswe futhi abunjwe ngokushesha ukuze kugcinwe ukwakheka kwebhamuza nokuvimbela ukuwa kwebhamuza. Enqubweni yangempela ye-extrusion foaming, isici esibalulekile esithinta ikhwalithi yemikhiqizo enegwebu ukulawula ukukhiqizwa nokukhula kwamabhamuza ukuze akhe izakhiwo zamaseli ezincane, ezifanayo nezizimele.
