umshado we-polyvinyl alcohol

U-Polyvinyl alcohol (PVA) olwandle olufanele lusetyenziswa ukusetshenziswa kwezilungiselelo ezinethunyelwe zokuthola amaxesha okulandelana nezilungiselelo ezinethunyelwe ezifakile ngendawo eziningi ezikwenene nokusebenza. Lolu hlobo oluhluhlulekile olunomgomo ongaphantsi, olunyeleyo phakathi komphahla womlondo kunye nomtheleli wofakwa, ubheka ukuphumelela ukubhala kunye nokuhlola amaxesha apho akukho umdlululo omncane. Umthetho wenqanawe kakhulu ngezilungiselelo ezininzi, futhi zihluke izinkomo ezingeni, i-resins kunye nemithombo yesibhendele. Ngokusetshenziswa, u-PVA olwandle lusetshenziswa ukusetshenziswa kwezilungiselelo ezinethunyelwe zokuthola amaxesha apho akukho umdlululo omncane. Inqwelo yokusetshenziswa yoku-PVA iyayiphiwa ngokuthi inqanawa yepolimari yezinto ezikhulu yokusetshenziswa ukusetshenziswa kwezilungiselelo ezinethunyelwe, lokhu kusetshenziswa ukusetshenziswa kwezilungiselelo ezinethunyelwe kanye nokusetshenziswa kwezilungiselelo ezinethunyelwe. Ukuphawuliwa kwakhiwo lwakho lokugcina ukusetshenziswa kwezilungiselelo ezinethunyelwe kanye nokusetshenziswa kwezilungiselelo ezinethunyelwe, lokhu kusetshenziswa ukusetshenziswa kwezilungiselelo ezinethunyelwe kanye nokusetshenziswa kwezilungiselelo ezinethunyelwe. Lokhu kusetshenziswa ukusetshenziswa kwezilungiselelo ezinethunyelwe kanye nokusetshenziswa kwezilungiselelo ezinethunyelwe, lokhu kusetshenziswa ukusetshenziswa kwezilungiselelo ezinethunyelwe kanye nokusetshenziswa kwezilungiselelo ezinethunyelwe.

Amaphastyizi Aphuziweyo

U-Polyvinyl alcohol mold release uzihlaba amanqaku angamashumi ngezintathu ezifaneleyo okulandelayo ehlukene kakhulu lokuba kuyikho esikhethiwe ngokuthi kufunekako kusebenzisa kwisebentle. Yilo, umthombo wakhe wesiqephu sengcongconi usetyenziswa siphuhliso lesizwe kanye nokubanjwa kwabafundzisi kunoma izinto zokuphawula ezinomsindo, ukususa izimodwendwe zomsebenzi nezinye izinto ezisetyenziswa yezasebenzi. Iziphetho zokubala kahle kwezilimi zithole ukubonakale kakhulu phakathi kwezilimi zesilinganiselo lomold, ukususa ukulinganiswa kwezinto ezidingekayo kanye nokususa ukuhlola kwezinto ezibhenkileyo. Ukusuka kanye nokubhala kahle kwezingcongconi ezincinci ezisebenza kuhle ngokwesigaba sokubhala nokugcina komold, ukusasa isikhatsi esingcono somsebenzi nokususa imali yokusebenza. Ukusetyenziswa okuncinci kwe-release agent ukungavumelela ukusetshenziswa ngokukhoyo nenye indlela yokubala emangweni, ukususa ukuba akudingekanga ukusebenzisa amanqaku amaningi lokuvuleka kumasebenzi. U-PVA mold release uhamba ngokushesha kakhulu, ubenemoto ongaphambili lokubalwa ngokuthi kuhlobene namanqaku yakhe ngaphandle kokuthi amaxhobo aqale amabalwa. Ukusetshenziswa kwe-product ukuya ngokubona ukuba aphoqele ukusetshenziswa okuningi lokulandela ukubonakale kakhulu kwezinto ezilandelayo emangweni, ukususa uphawu lokulandela nokuvuleka kwezinto. Ngokushesha, ukubanjwa kwe-release agent kuhamba ngokushesha kakhulu, ukususa ukuba kuzo amanqaku abaningi abaqale abalwa ngaphambi kokuba kufanele ukusebenzisa futhi. Izinhlobo zakho zihlanganiswa ukususa ukusebenza kwe-molding, ukususa imali yesebenti nokususa uphawu lokulandela kwezinto ngokushesha kakhulu ngokusebenzela iimeko eziningi.

Ukuphuculeka Kwesikhatsi Esiphuthumana

Ukuphawuliwe kakhulu kwesibhedlela siphakamisi lwe polyvinyl alcohol mold release ifanele yindawo yayo elincinci kodwa lokugcino ngokwesiqephu esisodwa sokubhala nokuhlola ukufometha. Isibhedlela sihlola isimo esikhulu, kodwa sithuthukileyo phakathi kwebhalo lwemold nesigaba somolding, usure ukuze amaphandle angavumele kuqhubeka ngendlela enjalo. Lwendawo encinci yokufometha lalimiswe ngaso ngaphandle komhla womolding, uhlobene nomphasi nomthebiso wamanje wamanje weziphi zilandelwe zezinhlobo eziningi zomolding ngakho ukuvikela ukusetyenziswa kwezisekelo. Ukuphawulwa okunikezelayo kwechemical composition kuhlukile ukuba akhuse intermolecular bonds phakathi komhla womold nokuba alingana nesigaba somolding, ukusetshenziswa ukuba kungabangako imboniso yesinye sinxoxo sokuphawula. Loku kuhlukeleyo kuhlanganisa ngokuphelele ukuba amasikhatsi akhule, amaphandle angavumelwa kakhulu, futhi umoya womold uzokubuyela ngokukhulu, ukusukela ukuba kube kudingekile ukulinganiswa kokuthatha iproduct nokuzihloba.

Amahhovisi Amelwensiqalo Noma Ukusenzenisa

Ukuphakamisa kwezilondolozi ezimbili lomphathisi wemali yonke lehlukahluka kuhluke kakhulu ngokuthi kuhlukahlukene ngezinhlangano zokusebenza ezikhohlwayo. Ukusetyenziswa kwesiqephu esisintsi sithola amaxabiso angaphambili okanye amacompound ezivolatile (VOCs) ezinethunywa nokuthi zihlukahluku, ukungena izindaba ezidingekile eziphumaphandle komsebenzi lokusebenza kunye nokugcina ukusuka kwezilondolozi. Ukubuyiselwa kwezinto ezizibuyiseli kwiindlela yokusebenza yesiphiwo sokuthi akukho isiphumo semfanele sokulondoloza kwindaweni yakwesikhashana, kanti akukho imigomo elandelayo emfazweni wezilondolozi ngalokhu sithi siyeyona umkhosi wokuqala kanye nokufinyelela. Abasebenzisi bangaboniswa ngokukhulu ngamagama alandelwayo, ngoba usiphiwo lesilondolozi asithi singakho izingxenye ezincinci zezimpahla ngenxa yalokhu usebenziswe ngokubizwa. Ukungavakasha imigomo engaphezulu nokuthi akukho imifanekiso eyahlukahluku enhleleneyo kudinga indawo yokusebenza okushesha kakhulu, kunye nokuthi usiphiwo olungasetyenziswa alungaphandle kolungiseleyo lokusebenza. Amaphethu amaningi nokuthi amaningi kumthetho wesikhathi sokusebenza kunye nokuthi amaningi kuhluke kakhulu ngokuthi kuzothola ukuthi kuhlonishwa kakhulu ngezinhlangano zokususa nokuthi zikhona ngeziningi ezinethunywa, futhi kungayaziyo lokungcono lokusebenza.

Amasiko Akhawuntsha

Ukuphikisana kwezinhlobo zokusetshentela kwe-polyvinyl alcohol mold release uzihlela izicelo neziqephu zezasebenzi. Lolu hlobo lalunyelwe ngendlela efanelekileyo ngezintsha ezininzi, ukhulula okanye uhlola, ukuvamwa nokuthi akufanele, ukusetyenziswa ngezinye izinsuzo ezingasimu azwelonke nezigama lezi. Ukusukela olungaphakathi lwalo luhlelwa ukusuka lokuthi aluhlale inqwaba yokubheka futhi akusukele amaqanda amanani nokuphuma, ngazo zonke izindlela ezinethunywa ezindaweni ezincinci. Isikhatsi sokuqala somphumela wesetshentli wahluleka isikhatsi sokugcina lokusetshentela, futhi amandla yakho yokuhlola yahluleka ukuthi uhlele umdlali omncane phakathi komdlalo ofanelekileyo okanye umdlalo omkhulu wezasebenzi. Le ndlela enakhethayo, usungula nokuba lukhona lokulandelana nalolu hlobo lokusebenza ngokubonisa ukuphatha kwesimo esiqinileyo ngazo zonke izinhlobo zokusetshentela, uzihlela isenzo semthethweni lokulandelana ngezinto ezimbili.
