Indima yomlawuli we-PVC foaming

1. Thuthukisa kakhulu amandla okuncibilika
Ngokuthuthukisa ukuhlangana kokuncibilika kwe-PVC, ukufaka ngempumelelo igesi ekhipha igwebu, ukuvimbela ukuhlangana noma ukuqhekeka kwama-bubble, ukuqinisekisa isakhiwo seseli esizinzile nesisakazeke ngokulinganayo.
Isakhiwo senethiwekhi esakhiwe yizici eziphakeme zesisindo sama-molecule (ngokuvamile ezingaphezu kwezigidi ezintathu) sithuthukisa kakhulu ukumelana kokuncibilika kokuncibilika, sinciphisa ingozi yokuphuma kwegesi kanye nokuwa kwama-bubble.
2. Lungiselela isakhiwo sembobo kanye nokufana
Lawula ukuqina kokuncibilika ukuze ugcine isimo esizinzile samabhamuza ngesikhathi sokunwetshwa, ugweme ukuthi amabhamuza aseduze angachotshozwa ngenxa yokunganele kwamandla okuncibilika.
Kwakha isakhiwo seseli esincane nesiminyene esivaliwe (usayizi wembobo ungalawulwa ngaphakathi kwama-80-150 μ m), kunciphisa ubuningi bomkhiqizo ngenkathi kuthuthukiswa amandla awo okusebenza.
3. Thuthukisa ukusebenza kokucubungula
Khuthaza ukwenziwa kwepulasitiki: Sheshisa inqubo yokuncibilikisa ipulasitiki ye-resin ye-PVC, uthuthukise ukufana nokusebenza kahle kwepulasitiki, futhi unciphise umjikelezo wokukhiqiza.
Ukulungisa ukugeleza: ukulinganisela umsebenzi we-molecular chain, ukunciphisa ukumelana nokungqubuzana, ukuqinisekisa ukugeleza kokuncibilika okumaphakathi, nokugwema ukucutshungulwa kwe-coke eshisa kakhulu.
Thuthukisa ukuzivumelanisa nezimo kwenqubo: Iyahambisana namafomula okugcwalisa okuphezulu (njengokwengezwa kwe-calcium powder ephezulu), ifanele izidingo ezahlukene zenqubo njengokugqwala kwamahhala kanye nokugqwala kwesikhumba.
4. Thuthukisa ikhwalithi yomkhiqizo
Ukushelela komphezulu: Khuthaza ukusabalala kwezithasiselo, susa amaphutha omphezulu, wenze umphezulu wamabhodi/amapayipi e-foam ube bushelelezi futhi uthambile, futhi wenze kube lula ukuphrinta noma ukumboza okulandelayo.
Ukuqina kobukhulu: Lungiselela ukusatshalaliswa kokucindezeleka kwangaphakathi, nciphisa ukuguquguquka okubangelwa amazinga okushisa noma amandla angaphandle, thuthukisa ukunemba komkhiqizo nokuqina kwawo.
Ilula futhi Inamandla Aphezulu: Ukufinyelela ibhalansi phakathi kokuqina okuphansi (kufika ku-0.6g/cm³) kanye namandla aphezulu, ngenkathi futhi kucatshangelwa ukusebenza komsindo kanye nokuvikela ukushisa.
5. Isebenza kabanzi futhi ihambisana nemvelo
Ifanelekela izinkambu ezahlukahlukene njengezakhi zokwahlukanisa, amaphrofayili efenisha, izinto zezicathulo, amapayipi, njll., ihlangabezana nezidingo zezinto zokwakha ezilula kanye nezimpahla zabathengi ezisezingeni eliphezulu.
Ihlanganiswe nezithasiselo ezinobungani nemvelo ezifana neziqinisi ze-calcium ne-zinc, ihambisana nezindinganiso zomhlaba wonke njenge-REACH/ROHS futhi ifanelekela imikhiqizo yezinga lokuxhumana kokudla. Siyakwamukela ukuthenga i-Bangtai Manufacturing Foam Regulator. Singayihlela ngokwezifiso ngokwezidingo zakho futhi silwele ukuhlinzeka amakhasimende ngemikhiqizo eyanelisayo kanye nezinsizakalo ezicatshangelwe kahle!
