Ingcaciso eneenkcukacha ngomsebenzi, idosi, kunye nomgaqo womlawuli we-PVC foaming

一、Indima yomlawuli we-PVC okhupha amagwebu
Kwinkqubo yokuvelisa iimveliso ze-PVC foam, umlawuli we-PVC foam udlala indima ebalulekileyo. Imisebenzi yakhe ephambili ibonakala kwezi zinto zilandelayo:
1. Ukuphucula amandla okunyibilika: Iimodifier ze-PVC foam zinokuphucula kakhulu amandla okunyibilika kwePVC, zenze ukuba isebenze ngakumbi ekugqumeni iigesi kunye nokuthintela ukuphuma kwegesi kunye nokuwa kweeseli. Lo msebenzi ubalulekile ekugcineni uzinzo lwesimo seseli ngexesha lenkqubo yokugquma, nto leyo enceda ukufumana isakhiwo sokugquma esifanayo.
2. Lungisa ulwakhiwo lweseli: Ngokulungisa i-viscoelasticity ye-PVC melt and foaming regulator, qinisekisa ukuba iiseli zigcina imo ezinzileyo ngexesha lenkqubo yokukhula, uphephe ukuqhekeka ngenxa yokucinezelwa kweeseli ezikufutshane okanye amandla angonelanga okunyibilika. Ulwakhiwo lweseli oluphuculweyo lwenza usasazo lwangaphakathi loxinzelelo lwebhodi yefoam lufane ngakumbi xa luphantsi kwezinto zangaphandle, ngaloo ndlela luphucula uzinzo olunemilinganiselo.
3. Khuthaza inkqubo yokwenza iplastiki: Abalawuli befoam banokukhuthaza ukwenza iplastiki ye-resin ye-PVC, benze iplastiki ye-PVC ifane ngakumbi, ngaloo ndlela kuphuculwe ukukhazimla komphezulu kunye nomgangatho wemveliso yemveliso.
Idosi kunye nezinto ezichaphazela umlawuli we-PVC foaming
Umlinganiselo wolawulo lwe-PVC foaming uyahluka ngokuxhomekeke kwiimveliso zabavelisi abahlukeneyo, izixhobo ezisetyenzisiweyo, iimeko zenkqubo, kunye neemfuno ezithile zemveliso. Ngokubanzi, umthamo wayo uphakathi kwe-1% kunye ne-5%. Olu luhlu lusekelwe kumava okwenyani emveliso kunye nenani elikhulu ledatha yovavanyo, kwaye lungasetyenziswa njengesalathiso.
Nangona kunjalo, kubalulekile ukuqaphela ukuba ubungakanani bomlawuli we-foam osetyenzisiweyo abungcono kangako. Umlawuli we-foam ogqithisileyo unokukhokelela ekuphuzeni kakhulu, nto leyo ebangela inani elingalawulekiyo kunye nobukhulu beembobo, nto leyo echaphazela umgangatho wemveliso. Ngokwahlukileyo koko, umlinganiselo onganeleyo unokukhokelela ekuphuzeni ngokwaneleyo, ukwanda kwenani leziphene, kunye nokunciphisa umgangatho wemveliso.
Ke ngoko, xa kumiselwa idosi yomlawuli we-PVC foaming, izinto ezininzi ezifana neenjongo zemveliso, amandla ezixhobo, kunye neemeko zenkqubo kufuneka ziqwalaselwe ngokupheleleyo ukuze kufunyanwe indawo efanelekileyo yokulinganisela.
Ngoku, umgaqo wokusebenza we-PVC foaming regulator
I-PVC foaming regulator ngokuyintloko sisixhobo sokuncedisa ukucubungula i-acrylic, esinobunzima be-molecular obuphezulu kakhulu kunobo bezixhobo zokuncedisa ukucubungula ngokubanzi. Ngexesha lokucubungula, ii-molecular chains ezinde ze-molecular regulator foaming ziya kugoba kwaye zinamathele kwii-molecular chains ze-PVC, zenze isakhiwo esithile senethiwekhi. Esi sakhiwo asigcini nje ngokuphucula amandla okunyibilika kwe-PVC, kodwa sikwaphucula iipropati zomzimba ezifana nokuthamba kunye nokwandiswa kokunyibilika, ngaloo ndlela kunceda ukugqunywa kwamaqamza kwaye kuthintele ukuhlangana okanye ukuqhekeka kwawo.
Ukongeza, abalawuli be-foam banokulawula ukutyibilika kwee-PVC molecular chains, banciphise ukungqubana phakathi kwee-molecular chains, kwaye benze i-PVC resin ihambe ngcono ngexesha lokucubungula. Oku kunceda ukufumana iimveliso ze-foam ezibukeka kakuhle.
Ngamafutshane, abalawuli be-PVC foam badlala indima engenakutshintshwa kwimveliso yeemveliso ze-PVC foam ngokusebenzisa umgaqo wabo okhethekileyo wokusebenza. Abakwazi nje ukuphucula umgangatho kunye nokusebenza kweemveliso, kodwa banokwenza ngcono iinkqubo zemveliso kwaye bandise ukusebenza kakuhle kwemveliso. Ke ngoko, kubalulekile ukukhetha iarhente efanelekileyo yokwenza i-foam kwinkqubo yemveliso yeemveliso ze-PVC foam.
