Indlela ipayipi lepulasitiki le-PVC elimelana ngayo nokushisa okuphezulu yokwakha

Amapayipi epulasitiki e-PVC-Uama-resin e-thermoplastic angenawo ukwakheka enziwe nge-vinyl chloride monomer ngokusabela kwe-polymerisation kanye nezinye izithako (njengeziqinisi, izinto zokugcoba, izigcwalisi, njll.). Amapayipi epulasitiki e-pvc-U aguqulwa ngokuxubana namanye ama-resin ngaphezu kwezithasiselo, okwenza abe nenani elibonakalayo elisebenzayo. Lawa ma-resin yi-CPVC, i-PE, i-ABS, i-EVA, i-MBS, njll. I-UPVC ine-viscosity ephezulu yokuncibilika kanye nokugeleza okubi, futhi noma ngabe ingcindezi yomjovo kanye nokushisa kokuncibilika kukhushuliwe, ushintsho lokugeleza alubalulekile. Ngaphezu kwalokho, izinga lokushisa lokubumba le-resin liseduze kakhulu nokushisa kokubola kokushisa, futhi izinga lokushisa elingabumba lincane kakhulu, okuyinto enzima ukuyibumba.
Izici:
Ipayipi lepulasitiki le-PVC-U linezakhiwo ezinhle kakhulu zokugoba, ukumelana okuhle kwamakhemikhali, amandla omshini, ukumelana nokuguga kanye nokumelana nokushisa.
Umthamo wokuthwala:
Amapayipi epulasitiki e-PVC-U angamelana nokucindezela okunzima kwesinyathelo ngaphandle kokuphuka.
Izindawo zokusetshenziswa kwamapayipi epulasitiki e-PVC-U:
Ukugoqa izintambo zikagesi, ukugoqa izintambo zokuhlobisa, okufanele ukuthuthwa koketshezi namafutha, ukuvikelwa kwezintambo zikagesi, ukuvikelwa kwama-harnesses ezintambo zezimoto, imishini yamathuluzi omshini, amathuluzi okuzenzakalelayo, njll.
Ipayipi lepulasitiki le-PVC-Uilula, kulula ukuyiphatha nokulayisha ipayipi lepulasitiki le-PVC-U ilula, amandla adonsela phansi athile ayi-1/5 kuphela yepayipi lensimbi, kulula ukuyiphatha, ukuyilayisha nokulayisha, ukwakhiwa, kungonga izindleko zokwakha. Ipayipi lepulasitiki le-PVC-U linokumelana okuhle kakhulu nokugqwala, ukumelana okuhle kwamakhemikhali Ipayipi lepulasitiki le-PVC-U linokumelana okuhle kakhulu ne-asidi, ukumelana ne-alkali, ukumelana nokugqwala, embonini yamakhemikhali, ukudonsa amanzi amdaka, indle yendle kanye nokunye ukusetshenziswa kufanelekile kakhulu. Ipayipi lepulasitiki le-PVC-U linodonga olubushelelezi kanye nokumelana okuphansi koketshezi, i-coefficient yayo yobulukhuni ingu-0.009 kuphela, ephansi kunezinye amapayipi, futhi ku-calibre efanayo, izinga lokugeleza liphakeme futhi akukho sikali esinamathiselwe. Ipayipi lepulasitiki le-PVC-U linamandla amahle okusebenza Ipayipi le-PVC linokumelana okuhle nokucindezela kwamanzi kanye namandla okushaya, ekushiseni kwegumbi, ipayipi lepulasitiki le-PVC-U lifanelekela amaphrojekthi okufaka amapayipi ngaphansi kwezimo ezahlukahlukene.
Ipayipi lepulasitiki elihle le-PVC-U elifakwe ugesi linokufakwa kogesi okuphezulu, elifanele intambo, ipayipi lekhebula, lingasetshenziswa kabanzi kwezokuxhumana, amapayipi kagesi kanye namapayipi entambo yokwakha. Ipayipi le-PVC alithinti ikhwalithi yamanzi, njengoba kuqinisekiswe yimiphumela yokuhlolwa kokuncibilika, alithinti ikhwalithi yamanzi, awekho “amanzi abomvu”, ipayipi elivamile lamanje lokusatshalaliswa kwamanzi. Ukuncibilika kwamanzi okuhle Ipayipi lepulasitiki le-PVC-U kungakhathaliseki ukusetshenziswa kwe-socket ephilayo noma inhlanganisela ye-TS socket, linokuqina kwamanzi okuhle, yize iminyaka eminingi linokucindezela kwamanzi ekusatshalalisweni kwamanzi, kodwa futhi alinawo ubungozi bokuvuza. Ukwakhiwa kwepayipi lepulasitiki le-PVC-U elilula ngokushesha nangokulula, izindleko zephrojekthi yokwakha ziphansi.
Ipayipi lepulasitiki le-PVC-U
Ipayipi le-PVC-U njengezinto zokukhipha amanzi, ngenxa yezici zalo, ukusetshenziswa kwezinga lokushisa lokukhipha amanzi eliqhubekayo endlini akufanele libe ngaphezu kuka-40 ℃, kuyilapho izinga lokushisa lokukhipha amanzi ngokushesha akufanele libe ngaphezu kuka-80 ℃. Lokhu kuvame ukunganakwa futhi kungaholela ekuvuza emajoyintini ngesikhathi sokusetshenziswa isikhathi eside, ikakhulukazi kwamanye amalabhorethri e-biochemical ezakhiweni zelebhu zaseyunivesithi lapho izinkinga ezinjalo zivame ukwenzeka khona. Futhi ikhambi lingaba ukufaka ezinye izinto zepayipi lokukhipha amanzi lensimbi esikhundleni salo. Ngesikhathi esifanayo ipayipi le-PVC kufanele lifakwe ukuze kugwenywe ukuhlelwa kwemithombo yokushisa esihlokweni, okufanele kuqashelwe ikakhulukazi ekufakweni kwemisele yasekhishini, ukuqinisekisa ukuthi ibanga eliphakathi kwemisele nesitofu, uma kungenjalo kufanele ligwenywe kufanele lithathe izinyathelo zokuvimbela.


Ipayipi lokukhipha amanzi le-PVC-U uma lisetshenziswa ezakhiweni eziphakeme. Abanye onjiniyela kanye nochwepheshe abathathi zinyathelo zokuvimbela ukungena komlilo njengoba kuchazwe emithethweni yobuchwepheshe. Indlela efanele yile: ngokwemithetho yobuchwepheshe, i-riser ibekwa obala futhi ububanzi bayo bepayipi bukhulu noma bulingana no-110mm~l,-J, esikhuphukeni esiwela phansi. Kufanele kuthathwe izinyathelo zokuvimbela ukungena komlilo; ububanzi bepayipi obukhulu noma obulingana no-110mill wepayipi elivulekile eliwela emthonjeni wepayipi, i-riser yepayipi, lapho iwela emthonjeni wepayipi, udonga lwembobo yepayipi, kufanele kuthathwe izinyathelo zokuvimbela ukungena komlilo. Amapayipi amakhulu awela phansi akufanele awele izindonga zokuhlukanisa umlilo kanye nezingodo zomlilo; uma kungenakugwenywa ukwenza kanjalo, kufanele kuthathwe izinyathelo zokuvimbela ukungena komlilo kuzo zombili izinhlangothi zodonga lapho ipayipi liwela khona, njenge-casing engangeni manzi, indandatho yokuvimba umlilo, njll.
