Cov yeeb nkab yas pvc tiv taus kub npaum li cas rau kev tsim kho

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, EVA, MBS, thiab lwm yam. UPVC muaj viscosity yaj siab thiab fluidity tsis zoo, thiab txawm tias qhov siab txhaj tshuaj thiab qhov kub yaj nce ntxiv, qhov kev hloov pauv ntawm 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 molded yog nqaim heev, uas yog ib yam khoom nyuaj rau pwm.
Yam ntxwv:
Cov yeeb nkab yas PVC-U muaj cov yam ntxwv zoo heev, tiv taus tshuaj lom neeg, muaj zog, tiv taus kev laus thiab tiv taus kub.
Load-bearing muaj peev xwm:
Cov kav dej yas PVC-U tuaj yeem tiv taus qhov hnyav ntawm kev taug kev yam tsis muaj kev tawg.
Cov chaw siv cov yeeb nkab yas PVC-U:
Cov hlua khi hluav taws xob, cov hlua khi kho kom zoo nkauj, tsim nyog rau kev thauj cov kua thiab roj, kev tiv thaiv kab hluav taws xob, kev tiv thaiv cov hlua khi tsheb, cov cuab yeej siv tshuab, cov cuab yeej siv tshuab, thiab lwm yam.
Cov yeeb nkab yas PVC-UCov yeeb nkab yas PVC-U yog lub teeb, yooj yim rau kev tuav thiab thauj khoom, lub zog 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, tshuaj lom neeg zoo heev Cov yeeb nkab yas PVC-U muaj kev tiv thaiv acid zoo heev, alkali tsis kam, corrosion tsis kam, 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, tus nqi ntws siab dua thiab tsis muaj nplai txuas. Cov yeeb nkab yas PVC-U muaj lub zog kho tshuab zoo Cov yeeb nkab PVC muaj kev tiv thaiv zoo rau lub zog dej thiab lub zog cuam tshuam, ntawm chav tsev kub, Cov yeeb nkab yas PVC-U yog qhov tsim nyog rau cov haujlwm kav dej hauv ntau yam xwm txheej.
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 tau lees paub los ntawm 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 TS ua ke, muaj dej nruj zoo, txawm tias muaj dej ntau xyoo los ntawm kev siab rau kev faib dej, tab sis kuj tsis ua rau muaj kev pheej hmoo ntawm kev xau. Kev tsim cov yeeb nkab yas PVC-U yooj yim ua tau sai thiab yooj yim, tus nqi tsim kho qis.
Cov yeeb nkab yas PVC-U
Cov yeeb nkab PVC-U ua cov khoom siv ntws dej, vim nws tus kheej cov yam ntxwv, kev siv qhov kub ntawm cov dej ntws hauv tsev yuav tsum tsis pub tshaj 40 ℃, thaum qhov kub ntawm cov dej ntws tam sim ntawd yuav tsum tsis pub tshaj 80 ℃. Qhov no feem ntau raug saib tsis taus thiab tuaj yeem ua rau muaj kev xau ntawm cov pob qij txha thaum siv ntev, tshwj xeeb tshaj yog hauv qee lub chaw soj nstuam biochemical hauv cov tsev kuaj mob hauv tsev kawm ntawv qib siab uas muaj teeb meem zoo li no feem ntau tshwm sim. Thiab qhov kev daws teeb meem tsuas yog hloov lwm cov yeeb nkab ntws dej hlau. 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 kav dej 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.
