Cov kav dej yas PVC-Uyog cov thermoplastic resins amorphous ua los ntawm vinyl chloride monomer los ntawm polymerisation reaction ntxiv rau qee yam additives (xws li stabilizers, lubricants, fillers, thiab lwm yam). pvc-U yas kav dej raug hloov kho los ntawm kev sib xyaw nrog lwm cov resins ntxiv rau cov additives, ua rau lawv muaj txiaj ntsig zoo. Cov resins no yog CPVC,PE, ABS,YU, MBS, thiab lwm yam. UPVC muaj qhov viscosity siab thiab tsis muaj zog, thiab txawm tias qhov siab txhaj tshuaj thiab qhov kub yaj nce ntxiv, qhov kev hloov pauv ntawm qhov fluidity tsis tseem ceeb. Tsis tas li ntawd, qhov kub molding ntawm cov resin yog ze heev rau qhov kub thermal decomposition, thiab qhov kub thiab txias uas tuaj yeem pwm yog nqaim heev, uas yog cov khoom siv nyuaj rau pwm.
Cov yam ntxwv: PVC-U yas yeeb nkab muaj cov yam ntxwv zoo heev, tiv taus tshuaj lom neeg zoo, lub zog kho tshuab, tiv taus kev laus thiab tiv taus kub.
Lub peev xwm thauj khoom: Cov kav dej yas PVC-U tuaj yeem tiv taus qhov siab ntawm ib kauj ruam yam tsis muaj kev tawg.
Cov chaw siv cov yeeb nkab yas PVC-U: cov xov hluav taws xob, cov xov dai kom zoo nkauj, tsim nyog rau kev thauj cov kua thiab roj, kev tiv thaiv kab hluav taws xob, kev tiv thaiv cov xov hlau tsheb, cov cuab yeej siv tshuab, cov cuab yeej siv tshuab, thiab lwm yam.
Cov yeeb nkab yas PVC-U yog lub teeb, yooj yim rau kev tuav thiab thauj khoom. Cov yeeb nkab yas PVC-U yog lub teeb, qhov hnyav tshwj xeeb tsuas yog 1/5 ntawm cov yeeb nkab hlau, yooj yim rau kev tuav, thauj khoom thiab thauj khoom, kev tsim kho, tuaj yeem txuag cov nqi tsim kho. Cov yeeb nkab yas PVC-U muaj kev tiv thaiv corrosion zoo heev, tiv thaiv tshuaj lom neeg zoo heev Cov yeeb nkab yas PVC-U muaj kev tiv thaiv acid, alkali, tiv thaiv corrosion zoo heev, rau kev lag luam tshuaj lom neeg, dej khib nyiab, dej phwj tuaj thiab lwm yam kev siv yog qhov tsim nyog heev. Cov yeeb nkab yas PVC-U muaj phab ntsa du thiab tsis tshua muaj kev tiv thaiv rau cov kua dej, nws cov coefficient roughness tsuas yog 0.009, uas qis dua lwm cov yeeb nkab, thiab hauv tib lub calibre, cov dej ntws loj dua, thiab tsis muaj nplai txuas.
Cov yeeb nkab yas PVC-U zoo rwb thaiv hluav taws xob muaj kev rwb thaiv hluav taws xob zoo dua, tsim nyog rau cov hlau, cov kav dej cable, tuaj yeem siv dav hauv kev sib txuas lus, cov kav dej fais fab thiab cov kav dej hlau hauv tsev. Cov yeeb nkab PVC tsis cuam tshuam rau qhov zoo ntawm dej, raws li cov txiaj ntsig ntawm kev sim yaj, tsis cuam tshuam rau qhov zoo ntawm dej, tsis muaj "dej liab", cov yeeb nkab tam sim no siv rau kev faib dej. Cov yeeb nkab yas PVC-U yaj tau zoo txawm tias siv lub qhov (socket) lossis lub qhov (socket) TS ua ke, muaj dej nruj zoo, txawm tias muaj dej ntau xyoo los xij, tab sis kuj tsis ua rau muaj kev pheej hmoo ntawm kev xau. Kev tsim kho yog yooj yim PVC-U cov yeeb nkab yas tsim kho sai thiab yooj yim, cov nqi tsim kho qis.
pvc-u yas yeeb nkab
Cov yeeb nkab PVC-U ua cov khoom siv ntws dej, vim nws tus kheej cov yam ntxwv, kev siv cov dej ntws tas mus li hauv tsev yuav tsum tsis pub tshaj 40 ℃, thaum qhov kub ntws tam sim ntawd yuav tsum tsis pub tshaj 80 ℃. Qhov no feem ntau tsis quav ntsej, kev siv cov txheej txheem mus sij hawm ntev yuav ua rau muaj kev xau hauv cov pob qij txha yeeb nkab, tshwj xeeb tshaj yog hauv lub tsev kuaj mob hauv tsev kawm qib siab hauv ib feem ntawm lub chaw kuaj mob biochemical feem ntau yuav tshwm sim qhov teeb meem no. Thiab qhov kev daws teeb meem tsuas yog hloov lwm cov yeeb nkab hlau ntws dej. Tib lub sijhawm, cov yeeb nkab PVC yuav tsum tau teeb tsa kom tsis txhob muaj qhov chaw kub hauv lub annex, uas yuav tsum tau sau tseg tshwj xeeb hauv kev teeb tsa cov kav dej hauv chav ua noj, kom ntseeg tau tias qhov deb ntawm cov dej ntws thiab lub qhov cub, yog tias tsis zam, yuav tsum ua cov kev ntsuas rwb thaiv tsev.
Cov yeeb nkab dej PVC-U thaum siv rau hauv cov tsev siab. Qee tus engineers thiab cov kws kho tshuab tsis ua cov kev ntsuas los tiv thaiv hluav taws nkag mus raws li tau teev tseg hauv cov cai tswjfwm. Txoj hauv kev zoo yog: raws li cov cai tswjfwm, lub riser raug tso rau qhib thiab nws lub raj txoj kab uas hla yog ntau dua lossis sib npaug rau 110mm ~ l,-J, ntawm lub riser hla hauv pem teb. Yuav tsum ua cov kev ntsuas los tiv thaiv hluav taws nkag mus; lub raj txoj kab uas hla loj dua lossis sib npaug rau 110mill ntawm cov yeeb nkab dej qhib hla ceg mus rau hauv lub qhov yeeb nkab, cov yeeb nkab riser, thaum hla lub qhov yeeb nkab, phab ntsa qhov yeeb nkab, yuav tsum ua cov kev ntsuas los tiv thaiv hluav taws nkag mus. Cov kav dej loj hla yuav tsum tsis txhob hla cov phab ntsa faib hluav taws thiab cov phab ntsa hluav taws; thaum nws tsis zam tau ua li ntawd, yuav tsum ua cov kev ntsuas los tiv thaiv hluav taws nkag mus rau ob sab ntawm phab ntsa qhov twg cov yeeb nkab hla, xws li lub plhaub tiv thaiv dej, lub nplhaib tiv thaiv hluav taws, thiab lwm yam.
