Chigawo chachikulu cha polyvinyl chloride, chomwe chimapangidwa ndi makina osindikizira monga kufananitsa mitundu, granulation, extrusion ndi kusindikiza.Pansi za PVC m'mphepete banding wapangidwa PVC utomoni, calcium carbonate ufa ndi zipangizo zosiyanasiyana wothandiza (monga stabilizer, DOP mafuta, ACR, stearic acid, titaniyamu dioxide, tona, odana ndi ukalamba wothandizila, etc.).(Ubwino wa banding m'mphepete umagwirizana kwambiri ndi chiŵerengero cha zinthu zoyambira).

Ntchito yaikulu ya m'mphepete banding Mzere ndi kuteteza ndi kukongoletsa gawo la bolodi, kuti kupewa zinthu zoipa chilengedwe ndi ntchito ndondomeko, kuwononga bolodi ndi kupewa volatilization formaldehyde mkati bolodi, ndi nthawi yomweyo. nthawi kukwaniritsa zotsatira za zokongoletsera zokongola.

Weruzani mtundu wa banding m'mphepete

1. Yang'anani mtundu ndi makulidwe a m'mphepete mwake.Mtundu wa pamwamba pa mzere wabwino wa m'mphepete ndiwofunikanso kwambiri.Kaya mtunduwo uli pafupi ndi zomwe mwakonda komanso zokongola.Ngati pamwamba ndi ovuta kwambiri ndipo pali zokopa, khalidwe silingakhale bwino kwambiri.Uwu ndiye mtundu wapamtunda wa banding m'mphepete.Zilibe chochita ndi khalidwe la zinthu zamkati m'mphepete banding, makamaka ndondomeko yopanga fakitale m'mphepete banding ndi kupanga luso luso antchito.Gulu labwino la m'mphepete ndi: pamwamba payenera kukhala yosalala, palibe kapena kuphulika pang'ono, palibe kapena mizere yaying'ono, yonyezimira, yowala kwambiri kapena ya matte (pokhapokha ngati pali zofunikira zapadera).

2. Yang'anani kumtunda kwa pamwamba ndi pansi pazitsulo zam'mphepete, ndipo ngati makulidwewo ndi ofanana, mwinamwake zidzachititsa kuti mgwirizano wa m'mphepete mwazitsulo ndi mbale, mzere wa guluu uwoneke kwambiri kapena kusiyana pakati pa mbale ndi mbale. m'mphepete mwake ndi yayikulu kwambiri kuti ingakhudze kukongola konse.Tsatanetsatane imatsimikizira kuchita bwino kapena kulephera, ndipo nthawi zambiri vuto laling'ono lazambiri limabweretsa zinthu zochititsa manyazi pomwe zotsatira zake sizili zabwino.

3. Kaya kudula m'mphepete kuli koyera, kaya pamwamba pa bandiyo m'mphepete mwake ndi yoyera kwambiri, komanso ngati mtundu wakumbuyo wa bandiyo uli pafupi ndi mtundu wapamtunda wa pepala lovuta.PVC m'mphepete banding imapangidwa makamaka ndi PVC ndi calcium carbonate kuphatikiza zowonjezera.Ngati kashiamu carbonate okhutira ndi okwera kwambiri, m'mphepete banding adzakhala woyera, kupindika adzakhala woyera, etc., zomwe zimatsimikizira kuti mtundu wa mankhwala si zabwino.

4. Kaya mphamvuyo ndi yabwino komanso ngati pali elasticity.Mphamvu yapamwamba imatanthauza kukana kwabwino kwa kuvala, ndipo khalidwe lofananira limakhalanso bwino.Ngati mphamvu ndi yokwera kwambiri, zimatanthauzanso kuti vuto la processing likuwonjezeka.Kutsika kwamphamvu kumatanthauza kukana kuvala kochepa komanso kutsika koletsa kukalamba.Kuphatikiza apo, molingana ndi zosowa za kupanga kwenikweni, nthawi zambiri ndikofunikira kudula m'mphepete mwamanja, kotero kuti mfundo zofewa zitha kupangidwa moyenera, ndipo makina omangira m'mphepete mwake amatha kupangidwa moyenerera mfundo zolimba.

5. Kaya zomatira zimagwiritsidwa ntchito mofanana, komanso ngati n'zosavuta kugwa pa bolodi panthawi yogwiritsira ntchito.
