Kusasitsa kulamulira: kusasitsa amatchedwanso kuchiritsa, ndi ndondomeko kuika filimu amene anaphatikizana mu uvuni (kucha chipinda), kuti wothandizila waukulu wa polyurethane zomatira, kuchiritsa wothandizila anachita crosslinking ndi kukhala ophatikizana ndi gawo lapansi mogwirizana padziko lapansi. .Cholinga chachikulu cha kuchiritsa ndi kupanga wothandizira wamkulu ndi wothandizira mankhwala mu nthawi inayake kuti achitepo kanthu kuti akwaniritse mphamvu zophatikizika bwino;kachiwiri, kuchotsa otsika otentha mfundo zotsalira zosungunulira, monga ethyl acetate, etc..
Kusasitsa ulamuliro makamaka ulamuliro wa kusasitsa kutentha ndi kusasitsa nthawi.Kusasitsa nthawi ya kutentha kwa msinkhu kumatsimikiziridwa ndi ntchito ya zomatira zomwe zimagwiritsidwa ntchito komanso zofunikira zomaliza za mankhwala.Mitundu yosiyanasiyana ya binder imakhala ndi kutentha kosiyana komanso nthawi zakucha.Kusasitsa kutentha ndi otsika kwambiri, m'munsimu 50 ℃, zimene zomatira ndi wodekha kwambiri;kusasitsa kutentha kwambiri, gawo lapansi filimu zina mpweya mpweya, zimakhudza gulu filimu ntchito ndi kuonjezera fungo, monga kukhwima nthawi yaitali kwambiri zimakhudzanso gulu filimu ntchito ndi kuonjezera fungo, amene makamaka chifukwa cha mpweya wa processing. imathandizira mu filimu ya polyethylene.
Ntchito yakucha chipinda: Ndi kuika filimu kuti wakhala anawonjezera mu kuphika chipinda (kucha chipinda), kuti wothandizila waukulu wa polyurethane zomatira, kuchiritsa wothandizila anachita kuwoloka kugwirizana ndi kuphatikizidwa ndi ndondomeko ya gawo lapansi mogwirizana. .Cholinga chachikulu cha kukhwima ndikupangitsa kuti wothandizira wamkulu ndi wochiritsa achitepo kanthu pakapita nthawi kuti akwaniritse mphamvu zophatikizika;chachiwiri, kuchotsa zosungunulira zotsalira ndi mfundo otsika otentha, monga ethyl acetate, etc., kuchepetsa kuchuluka kwa zotsalira zosungunulira ndi kuchepetsa fungo.
Kukhwima kumadaliranso pazifukwa zotsatirazi.
1, PET, BOPA, AL, CPP ndi mafilimu ena chifukwa cha kukana kutentha kwabwino, kutentha kwakukulu kwa shrinkage, kutentha kwa kusasitsa kumatha kuwonjezeka.Ndipo LDPE, BOPP, EVA ndi kutentha kwina kukhwima sikungakhale kokwera kwambiri;ambiri 50 ℃ - 65 ℃ pakati.
2, Nthawi yakukhwima yazinthu zokhala ndi guluu wambiri ndi yayitali.
3, Nthawi yakukhwima yazinthu ngati mipukutu yamakanema imatha kuchepetsedwa moyenera.
4, Nthawi yakukhwima yazinthu zokhala ndi ma longitudinal convex tendon imatha kutalika.
5, makulidwe a filimu, mpukutuwo m'mimba mwake ngati kuli koyenera kuwonjezera nthawi yakusasitsa.
6, pofuna kuchepetsa kuchuluka kwa zosungunulira zotsalira akhoza moyenerera anawonjezera kusasitsa nthawi.
7, malinga ndi ntchito ya mankhwala kusintha koyenera kwa kusasitsa nthawi.
Palinso inapita patsogolo kucha kwa ulamuliro kupanga.Tengani gulu filimu basi opangidwa za 1 mita yaitali, m'lifupi zonse, anaika mu uvuni pa madigiri 80 kwa mphindi 30, poona maonekedwe ake ndi koyamba mamasukidwe akayendedwe peeling mkhalidwe, yake kudziwika mavuto ndi miyeso.Ilinso ndi gawo lofunikira kwambiri pakuwongolera njira zowuma.
Pali zofunikira zotsatirazi za chipinda chokhwima.
1, kukula ndi malo a chipinda cha kusasitsa ziyenera kumangidwa molingana ndi kusungirako zosungirako, kuti ziwongolere kulowa ndi kutuluka kwa mpukutu wa filimuyo, chitseko chiyenera kutsegulidwa mosavuta.
2, kutalika kwa chipinda chokhwima nthawi zambiri kumakhala mamita 2-2.5, pamwamba pa nsanja, kusiya 5-10 masentimita pamwamba pa mabowo a mpweya, akhoza kukhala kunja, kapena kuwonjezera zenera laling'ono lotayirira nthawi zonse, ntchitoyo ndi kutulutsa fungo la kukhwima chipinda.
3, mashelefu a chipinda chokhwima akhoza kuikidwa lathyathyathya kapena azithunzi atatu alumali mtundu, malingana ndi zinthu zoyendera wa aliyense ogwira ntchito, koma osati filimu mpukutu mwachindunji woongoka kapena atagona pansi.
4, makoma anayi a chipinda chokhwima, zitseko, denga ndi kutchinjiriza zina, makamaka ntchito perlite, thovu bolodi, etc., zotsatira zake ndi kuonjezera nthawi kutchinjiriza, kupulumutsa magetsi, kuchepetsa ndalama ndi kutentha mozungulira chomwecho.
5, Kuwongolera kutentha.Kukhwima chipinda akhoza usavutike mtima ndi magetsi, nthunzi, Kutentha, etc., mosasamala kanthu za mtundu wa Kutentha, ayenera kukhala ndi zipangizo kutentha kudziletsa, m'chipinda ayenera kukhala mercury thermometer kuyesa ngati kutentha ndi anapereka yemweyo.
Malingaliro a kampani Guangdong Lebei Packing Co., Ltd.wadutsa QS, SGS, HACCP, BRC, ndi ISO certifications.Ngati mukufuna kudziwa zambiri ndipo mukufuna kuyitanitsa matumba, chonde tilankhule nafe.Tikupatsirani ntchito yabwino komanso mtengo wabwino.
