Matumba ophatikizana otsika osungunuka amapangidwa ndi EVA (copolymer ya Ethylene ndi Vinyl Acetate) resin, motero amatchedwanso matumba a EVA.EVA ndi polima ya elastomeric yomwe imapanga zinthu zomwe zimakhala "zonga mphira" mofewa komanso kusinthasintha. Izi zimakhala zomveka bwino komanso zonyezimira, kulimba kwa kutentha pang'ono, kukana kupsinjika, zomatira zomata zomwe sizingalowe m'madzi, komanso kukana ma radiation a UV. Ntchito zake zikuphatikiza filimu, thovu, zomatira zotentha zosungunuka, waya ndi chingwe, zokutira zakunja, kuyika kwa ma cell a solar, ndi zina zambiri.
Matumba athu otsika a batch ophatikizidwa ndi filimu amapangidwa ndi utomoni wa namwali wa EVA kuti atsimikizire mtundu wazinthu zomaliza. Timaona kuti zinthu zopangira zinthu sizili bwino chifukwa tikudziwa kuti zinthu zathu zizikhala zochepa pazogulitsa zanu.
Matumba ophatikizidwa ndi ma melt batch otsika amatanthawuza matumba omwe amagwiritsidwa ntchito kunyamula zowonjezera mphira ndi mankhwala pakuphatikiza. Kusankha matumba oyenera, nthawi zambiri timaganizira zinthu zotsatirazi:
- 1. Malo osungunuka
- Matumba okhala ndi malo osungunuka osiyanasiyana amafunikira pazosakanikirana zosiyanasiyana.
- 2. Zinthu zakuthupi
- Kulimba kwamphamvu ndi kutalika ndizo zikuluzikulu zaukadaulo.
- 3. Kukana mankhwala
- Mankhwala ena amatha kuwononga thumba lisanalowe mu chosakanizira.
- 4. Kuthekera kwa chisindikizo cha kutentha
- Kutentha kusindikiza thumba kungapangitse kuti zolembera zikhale zosavuta komanso kuchepetsa kukula kwa thumba.
- 5. Mtengo
- Kuchuluka kwa filimu ndi kukula kwa thumba kumatsimikizira mtengo wake.
Mutha kungotiuza zomwe mukufuna, akatswiri ku Zonpak adzakuthandizani kusanthula zomwe mukufuna. Ndipo nthawi zonse ndikofunikira kuyesa zitsanzo musanagwiritse ntchito zambiri.
Takhala tikufunsidwa funsoli pafupifupi tsiku lililonse. Yankho ndi "Ayi, sitingathe". Chifukwa chiyani? Ngakhale ndikosavuta kwa ife kupanga ndi kupereka zinthu zofananira, tikumvetsetsa kuti zipangitsa ogwiritsa ntchito kusokoneza kwambiri komanso kuwononga zinthu zosafunika. Zambiri mwazinthu zathu ndi zamtundu wamakasitomala komanso kukula kwake.Timatchula mtengo wamtundu uliwonse. Mtengo umasiyanasiyana malinga ndi zinthu, mawonekedwe, kukula, makulidwe a filimu, embossing, venting, kusindikiza ndi kuyitanitsa zofunika. Ku Zonpak, timathandizira makasitomala kusanthula zofunikira ndikusintha makonda oyenera ndi magwiridwe antchito / mtengo wabwino kwambiri.
ZopandaTMmatumba osungunula otsika ndi filimu amapangidwa mwapadera kuti aziphatikiza zida zophatikizira zamafakitale amphira, pulasitiki ndi mankhwala. Iwo ali ndi zotsatirazi wamba mbali.
1. Low Melting Point
Matumba a EVA amakhala ndi malo osungunuka otsika, matumba okhala ndi malo osungunuka amafanana ndi mikhalidwe yosakanikirana. Kuyikidwa mu mphero kapena chosakanizira, matumba amatha kusungunuka mosavuta ndikubalalika kwathunthu mumagulu a mphira.
2. Kugwirizana Kwambiri ndi Rubber ndi Pulasitiki
Zida zazikulu zomwe timasankha pazikwama zathu ndi filimu zimagwirizana kwambiri ndi mphira ndi mapulasitiki, ndipo zingagwiritsidwe ntchito ngati zosakaniza zazing'ono zamagulu.
3. Mapindu Ambiri
Kugwiritsa ntchito matumba a EVA kunyamula ndi kuyeza ufa ndi mankhwala amadzimadzi kungathandize kuti ntchito yowonjezereka ikhale yowonjezereka, ifike powonjezerapo molondola, kuthetsa kutayika kwa ntchentche ndi kuipitsidwa, kusunga malo osakanikirana kukhala oyera.
Malo osungunuka nthawi zambiri ndiye chinthu chofunikira kwambiri chomwe wogwiritsa ntchito amachiganizira posankha matumba osungunuka a batch kapena filimu yophatikizira mphira. Timapanga ndikupereka zikwama ndi filimu yokhala ndi malo osungunuka osiyanasiyana kuti zigwirizane ndi machitidwe osiyanasiyana amakasitomala. Malo osungunuka kuchokera ku 70 mpaka 110 deg C. alipo.
