Iibhodi ze-PVC ze-foam zisetyenziswa kuzo zonke iinkalo zobomi, ngakumbi kwizinto zokwakha. Ngaba uyazi ukuba zeziphi iingxaki ezinokuvela ngexesha lokuveliswa kweebhodi ze-PVC ze-foam? Ngezantsi, umhleli uya kukuxelela malunga nabo.
Ngokwemilinganiselo eyahlukeneyo yogwebu, inokwahlulwa ibe ngamagwebu aphezulu kunye namagwebu aphantsi. Ngokutsho kokuthamba kunye nokuqina kwe-foam texture, inokwahlulwa ibe yi-foam enzima, enzima kunye nethambileyo. Ngokwesakhiwo seseli, inokwahlulwa ibe yiplastiki ye-foam evaliweyo kunye neeplastiki ze-foam ezivulekileyo. Amaphepha amagwebu aqhelekileyo e-PVC anzima avaliweyo-iiseli ezisezantsi ezinogwebu. Amaphepha e-PVC amagwebu aneenzuzo zokuxhathisa umhlwa kwikhemikhali, ukuxhathisa kwemozulu, ukunqandwa komlilo, njl. njl kukhokelela kwiiseli ezinkulu kwiphepha le-foam kunye namacandelo amade e-longitudinal. Indlela ethe ngqo yokugweba ukuba amandla okunyibilika awanelanga kukuhamba emva kwee-roller ezintathu kwaye ucinezele ipleyiti ehlanganiswe kwi-roller ephakathi ngeminwe yakho. Ukuba amandla anyibilikayo alungile, unokuziva u-elasticity xa ucinezela. Ukuba kunzima ukuhluma emva kokucinezelwa, amandla okunyibilika aphantsi. Ngenxa yokuba i-screw structure kunye nendlela yokupholisa yahluke kakhulu, kunzima ukugweba ukuba ubushushu bufanelekile na. Ngokuqhelekileyo, ngaphakathi komthwalo ovumelekileyo we-extruder, iqondo lokushisa kwiindawo ezi-3-5 kufuneka libe liphantsi kangangoko. Ukuze ufumane iimveliso ezinogwebu ezifanayo kumaphepha amagwebu, kuyafuneka ukuba kuqinisekiswe ukuba izinto zePVC zinamandla anyibilikayo. Ke ngoko, umgangatho womlawuli ogwebu amagwebu ubaluleke kakhulu. Ngokomzekelo, ukongeza kwimisebenzi eyisiseko yoncedo lwenjongo jikelele, umlawuli okhupha amagwebu naye unobunzima bemolekyuli kunye namandla anyibilikayo, anokuphucula kakhulu amandla okunyibilika komxube wePVC kunye nokuthintela amaqamza kunye nokuqhekeka. , okubangela ukwakheka kweeseli ezifanayo kunye noxinano lwemveliso ephantsi, ngelixa likwaphucula iglosi yomphezulu wemveliso. Ewe kunjalo, idosi ye-ejenti yogwebu etyheli kunye ne-ejenti yogwebu olumhlophe kufuneka ihambelane.
Ngokweebhodi, ukuba ukuzinza akwanelanga, kuya kuchaphazela yonke indawo yebhodi kunye nomphezulu webhodi ukuba ujike, kwaye ibhodi ye-foam iya kuba yi-brittle. Isisombululo kukunciphisa ubushushu bokusebenza. Ukuba akukho phuculo, unokulungelelanisa ifomula kwaye ukwandise ngokufanelekileyo inani le-stabilizer kunye ne-lubricant. I-stabilizer yinkqubo yokuthambisa esekwe kwii-lubricants ezisuka kumazwe angaphandle ukuze kuphuculwe ubumanzi bemathiriyeli. Izinto ezikwaziyo ukumelana nobushushu zinokumanzi kakuhle. , ukumelana nobushushu obuhle; ukuchasana okunamandla kwemozulu, ukusasazwa kakuhle, ukuqina kunye neziphumo zokunyibilika; uzinzo obalaseleyo, plasticizing fluidity, uluhlu processing olubanzi, ukusetyenziswa olomeleleyo kunye nokuthanjiswa ancedisayo ngaphakathi nangaphandle. I-Lubricant ine-viscosity ephantsi, iipropati ezikhethekileyo eziphezulu, i-lubricity egqwesileyo kunye nokusabalalisa, kwaye isetyenziswa ngokubanzi kwi-plastic processing kunye namanye amashishini. Ineziphumo ezilungileyo zokuthambisa zangaphakathi nangaphandle; inokuhambelana kakuhle kunye ne-polyethylene, i-polyvinyl chloride, i-polypropylene, njl. Isetyenziswe njenge-dispersant, i-lubricant kunye ne-brightener ngexesha lenkqubo yokubumba iiprofayili ze-PVC, imibhobho, ukufakwa kombhobho, i-PE kunye ne-PP, ukunyusa izinga leplastiki, ukuphucula ukuqina kunye nokugudiswa. umphezulu weemveliso zeplastiki, kwaye inokutshintshwa nganye nganye, ikwenza kube lula ukufumana iingxaki ngokukhawuleza Naphi na apho ukhoyo, yisombulula ingxaki ngokukhawuleza. Ngokubhekiselele kwibhalansi ye-lubricant, isiliphu sangaphandle esaneleyo sibonakaliswa kwinto yokuba iqondo lobushushu kwindawo yesi-5 ye-extruder kunzima ukuyilawula kwaye ishushu ngokulula, okukhokelela kumaqondo obushushu aphezulu kumbindi wokuguqula, iingxaki ezinje ngamaqamza amakhulu, amaqamza, kunye ukutyheli phakathi kwebhodi, kwaye umphezulu webhodi awugudi; Ukutyibilika okugqithisileyo kuya kubangela ukuba imvula ibe yinto enzulu, eya kuzibonakalisa kwisakhiwo ngaphakathi kwesikhunta kunye nemvula ye-slip yangaphandle kumphezulu weplate. Iya kuphinda ibonakale njengeziganeko ezizimeleyo ezihamba ngasemva naphambili ngokungaqhelekanga kumphezulu wepleyiti. Ukunganeli kwangaphakathi ukutyibilika kuthetha ukuba kunzima ukulawula ubukhulu bebhodi, ephakathi kwaye ibhityile kumacala omabini. Ukutyibilika kwangaphakathi okuninzi kuya kukhokelela ngokulula kumaqondo obushushu aphezulu kumbindi wokuguqula.
