Inqubo yokubumba yomjovo yezinto ze-PVC

Izinto ze-PVC azibizi, ngokwemvelo ziphikisana nokuvuvukala, ziqinile futhi ziqinile, ukumelana namakhemikhali okuhle, izinga lokushwabana kwe-0.2-0.6%, imikhiqizo isetshenziswa ngokuya ngezinto zikagesi, imishini, ukwakhiwa, izidingo zansuku zonke, amathoyizi, ukupakisha, ngezici ze Izinto ze-PVC, ukuhlaziya inqubo yokubumba umjovo womkhiqizo imi kanje:

一、Izakhiwo zezinto ze-PVC

Ukuqina okushisayo kwe-PVC kubi, izinga lokushisa lokubumba kanye nezinga lokushisa lokubola liseduze, ukungahambi kahle, ukubukeka okulula ukwakha amaphutha amabi, ukumelana nokushisa kwe-PVC akukuhle, kulula kakhulu ukushisa, igesi ene-asidi nokugqwala kwesikhunta, ukucubungula. ingangeza i-plasticizer ukuze ikhulise uketshezi, - ngokuvamile kufanele ingeze izithasiselo ezizosetshenziswa, amandla ayo, ukufakwa kukagesi, ukumelana namakhemikhali okuhle.

二、 Isikhunta nesango design

Ukuze unciphise umjikelezo womjovo, lapho imbobo yomjovo iba mfishane iba ngcono, ingxenye ephambanayo kufanele ibe njengengadi, ububanzi obuncane bembobo yomjovo bube ngu-6 mm, ku-cone engadini, i-engeli yangaphakathi engu-5 degrees, okungcono kakhulu. ngemithombo ebandayo, imithombo ebandayo ingavimbela izinto ezingancibilikisiwe ezingaqinile emgodini, futhi lezi zinto zizothinta ukuqedwa kwendawo kanye namandla omkhiqizo.

I-die slope kufanele ibe phakathi kuka-0.50 no-10 ukuze kuqinisekiswe ukuthi umgodi unempahla eyanele yokukhipha umoya.Usayizi ojwayelekile wembobo yokukhipha umoya ngu-0.03-0.05mm ukushona no-6mm ububanzi, noma imvume engu-0.03-0.05mm eduze kwephinikhodi ngayinye yokukhipha.Idiyidi kufanele yenziwe ngensimbi engagqwali noma i-chrome eqinile.

三, inqubo yokubumba ye-PVC

I-PVC iyipulasitiki engezwani nokushisa.Ukushisa ngokweqile noma ukugunda ngokweqile kuzodala ukubola futhi kusakazeke ngokushesha, ngoba omunye wemikhiqizo yokubola (njenge-asidi noma i-HCI) izoba nomphumela we-catalytic, okuholela ekuwohlokeni okuqhubekayo kwenqubo, futhi i-asidi izoyiqeda insimbi futhi iyenze ishintshe.Uma iboshiwe, ungqimba oluvikelayo lwensimbi luzoxebuka, lubangele ukugqwala, okuyingozi kakhulu emzimbeni womuntu.Isilinganiso esivamile sobude bobude bobubanzi ngu-18~24:1, isilinganiso sezigaba ezintathu singu-3:5:2, futhi isilinganiso sokuminyanisa singu-1.8~2.Ukujula kwe-screw groove esigabeni sokuphakela kunconywa kanje:

Ijubane lomjovo kufanele lihambe kancane, ngaphandle kwalokho ukugunda ngokweqile kuzokwehlisa isithunzi.Uma usebenzisa i-UPVC ukukhiqiza imikhiqizo enezindonga eziwugqinsi ebushelelezi, kufanele kusetshenziswe isivinini sokujova esinamazinga amaningi.Uma imigqa ensundu ngokukhanyayo iphuma esangweni, kusho ukuthi ijubane lomjovo liphezulu kakhulu.ngokushesha.

Iphoyinti lesikulufu kufanele libe ne-engeli yangaphakathi engu-25~30 degrees.Uma isikulufu sisendaweni, ibanga phakathi kwethiphu nombhobho kufanele libe ngu-0.7~1.8mm.Isikulufu kumele senziwe ngensimbi engagqwali noma nge-chrome-plated.

1)I-Screw gasket: I-screw gasket iphakathi kuka-2~3mm, futhi ithuba elikhulu likhulu.

2)Ivolumu yomjovo: Isikhathi sangempela sokuhlala akufanele sidlule imizuzu emi-3.

3) Ukulungiselelwa kwezinga lokushisa lomphongolo:

Amazinga okushisa anikeziwe awokubhekisela kuphela, futhi ukulungiswa okufanele kwenziwa ngokuvumelana nezimo zangempela zomshini nezinto zokusetshenziswa, ezingase zidlule uhla olunconyiwe.

Izinga lokushisa lesigaba sokuphakelayo esimaphakathi engxenyeni engaphambili yomlomo wesikhunta (0C) 30-60 170-190 160-180 150-170

Umthamo womjovo osetshenziswa ku-140-160 ungama-20~85% wevolumu yomjovo wethiyori womshini.Uma umthamo womjovo osetshenziswayo ube mncane, kuba side isikhathi sokugcinwa kwempahla kanye nengozi enkulu yokuwohloka ngemva kokushisisa.cin.com

4) Isikhathi sokuhlala emgqonyeni:

Ngaphansi kokulawulwa kokushisa kwe-2000C (impahla yerabha), isikhathi esiphezulu sokuhlala somphongolo singadlula amaminithi angu-5, lapho izinga lokushisa liyi-2100C.

5) Isivinini sokujova:

Ijubane lomjovo kufanele lihambe kancane, ngaphandle kwalokho, impahla izokwehla ngenxa yokugunda ngokweqile.Ijubane lomjovo wezigaba eziningi kufanele lisetshenziswe uma usebenzisa i-UPVC ukukhiqiza imikhiqizo yodonga oluwugqinsi olubushelelezi kakhulu.Uma kunemigqa ensundu ngokukhanyayo ephuma esangweni, kusho ukuthi ijubane lomjovo liphezulu kakhulu.ngokushesha.
