Indlela umbhobho weplastiki we-PVC omelana ngayo nobushushu obuphezulu xa kusakhiwa

Imibhobho yeplastiki yePVC-Uzii-resin ze-thermoplastic ezi-amorphous ezenziwe nge-vinyl chloride monomer nge-polymerisation reaction kunye nezinye izongezo (ezifana neziqinisi, ii-lubricants, ii-fillers, njl.njl.). Iipayipi zeplastiki ze-pvc-U ziguqulwa ngokuxuba nezinye ii-resin ukongeza kwizongezo, nto leyo eyenza zibe nexabiso elibonakalayo. Ezi resin ziyi-CPVC, PE, ABS, EVA, MBS, njl.njl. I-UPVC ine-melt viscosity ephezulu kunye ne-fluidity embi, kwaye nokuba uxinzelelo lwe-injection kunye ne-melt temperature zinyukile, utshintsho kwi-fluidity alubalulekanga. Ukongeza, iqondo lobushushu be-resin lisondele kakhulu kubushushu bokubola kobushushu, kwaye uluhlu lobushushu olunokubunjwa luncinci kakhulu, into enzima ukuyibumba.
iimpawu:
Umbhobho weplastiki wePVC-U uneempawu ezintle zokugoba, ukumelana kakuhle neekhemikhali, amandla oomatshini, ukumelana nokwaluphala kunye nokumelana nobushushu.
Umthamo wokuthwala umthwalo:
Imibhobho yeplastiki yePVC-U inokumelana noxinzelelo olunzima lwenyathelo lonyawo ngaphandle kokuqhekeka.
Iindawo zokusetyenziswa kwemibhobho yeplastiki yePVC-U:
Ukugoba ucingo ngombane, ukugoba imikhono yokuhombisa, efanelekileyo ekuthuthweni kolwelo kunye neeoyile, ukhuseleko lwentambo yombane, ukhuseleko lweentambo zocingo zeemoto, oomatshini bezixhobo zoomatshini, izixhobo zokwenza izinto ngokuzenzekelayo, njl.
Umbhobho weplastiki wePVC-UIlula, kulula ukuyiphatha nokulayisha ipayipi yeplastiki yePVC-U ilula, umxhuzulane othile yi-1/5 kuphela yepayipi yentsimbi, kulula ukuyiphatha, ukuyilayisha nokulayisha, ukwakhiwa, kunokonga iindleko zokwakha. Ipayipi yeplastiki yePVC-U inokumelana nokugqwala okugqwesileyo, ukumelana neekhemikhali okugqwesileyo Ipayipi yeplastiki yePVC-U inokumelana nokugqwala okugqwesileyo, ukumelana ne-alkali, ukumelana nokugqwala, kushishino lweekhemikhali, ukuhambisa amanzi amdaka, amanzi amdaka kunye nezinye izinto zifanelekile kakhulu. Ipayipi yeplastiki yePVC-U ineendonga ezigudileyo kunye nokumelana okuphantsi kolwelo, i-coefficient yayo yoburhabaxa yi-0.009 kuphela, ephantsi kuneminye imibhobho, kwaye kwi-calibre efanayo, izinga lokuhamba liphezulu kwaye akukho sikali siqhotyoshelweyo. Ipayipi yeplastiki yePVC-U inamandla oomatshini amahle Ipayipi yePVC inokumelana nokuxinezeleka kwamanzi kunye namandla empembelelo, kubushushu begumbi, ipayipi yeplastiki yePVC-U ifanelekile kwiiprojekthi zemibhobho phantsi kweemeko ezahlukeneyo.
Umbhobho weplastiki wePVC-U olungileyo wokugquma umbane une-insulation yombane ephezulu, efanelekileyo kwiingcingo, kwi-cable conduit, ingasetyenziswa kakhulu kwiindlela zonxibelelwano, kwiipayipi zamandla nakwipayipi zentambo zokwakha. Umbhobho wePVC awuchaphazeli umgangatho wamanzi, njengoko kuqinisekiswe ziziphumo zovavanyo lokunyibilika, awuchaphazeli umgangatho wamanzi, akukho "manzi abomvu", umbhobho oqhelekileyo wangoku wokusasazwa kwamanzi. Ukunyibilika kwamanzi okuhle Umbhobho weplastiki wePVC-U nokuba kusetyenziswa i-socket ephilayo okanye indibaniselwano ye-TS socket, unokuqina kwamanzi okuhle, nangona iminyaka emininzi ucinezelekile ngamanzi ukuya kusasazo lwamanzi, kodwa awukho emngciphekweni wokuvuza. Ukwakhiwa kombhobho weplastiki wePVC-U olula wokwakha ngokukhawuleza nangokulula, iindleko zeprojekthi yokwakha ziphantsi.
Umbhobho weplastiki wePVC-U
Umbhobho we-PVC-U njengesixhobo sokukhupha amanzi, ngenxa yeempawu zawo, ukusetyenziswa kobushushu bokukhupha amanzi obuqhubekayo ngaphakathi akufuneki bube ngaphezu kwama-40 ℃, ngelixa ubushushu bokukhupha amanzi ngoko nangoko akufuneki bube ngaphezu kwama-80 ℃. Oku kuhlala kungajongwa kwaye kunokukhokelela ekuvuzeni kwamanzi kwiindawo zokudibana ngexesha lokusetyenziswa ixesha elide, ingakumbi kwezinye iilabhoratri zebhayoloji kwizakhiwo zelebhu zeyunivesithi apho iingxaki ezinjalo zihlala zivela khona. Kwaye isisombululo sinokuba kukutshintsha ezinye izixhobo zepayipi yokukhupha amanzi zesinyithi. Kwangaxeshanye umbhobho we-PVC kufuneka ufakwe ukuze kuthintelwe ukulungelelaniswa kwemithombo yobushushu kwisihlomelo, ekufuneka kuqatshelwe ngokukodwa ekufakweni kwemisele yekhitshi, ukuqinisekisa ukuba umgama phakathi kombhobho kunye nesitovu, ukuba akunjalo, kufuneka kuthathwe amanyathelo okukhusela.


Umbhobho wokukhupha amanzi wePVC-U xa usetyenziswa kwizakhiwo eziphakamileyo. Abanye oonjineli kunye neengcali abazithathi manyathelo okuthintela ukungena komlilo njengoko kuchaziwe kwimigaqo yobugcisa. Indlela echanekileyo yile: ngokwemigaqo yobugcisa, i-riser ibekwe ekuhleni kwaye ububanzi bayo bombhobho bukhulu kune okanye bulingana ne-110mm~l,-J, kwi-riser enqumla umgangatho. Kufuneka kuthathwe amanyathelo okuthintela ukungena komlilo; ububanzi bombhobho bukhulu kune okanye bulingana ne-110mill yombhobho ovulekileyo we-drainage cross-branch ungene emthonjeni wombhobho, i-riser yombhobho, ekunqamlezeni umbhobho wombhobho, udonga lomngxuma wombhobho, kufuneka kuthathwe amanyathelo okuthintela ukungena komlilo. I-Transverse mains akufuneki idlule iindonga zokwahlulahlula umlilo kunye nee-firewalls; xa kungenakuphepheka ukwenza njalo, kufuneka kuthathwe amanyathelo okuthintela ukungena komlilo kumacala omabini odonga apho umbhobho unqumla khona, njenge-casing engangeni manzi, iringi yokumisa umlilo, njl.
