Kuti mukhale ndi mphamvu, yowala komanso yopepuka, muyenera kupopuka PVC

PVC ya mtundu wozolowereka ndi mapepala okhala ndi phokoso lamtundu wolimba ndi lachinthu chopanda pake. Ngati PVC yotupa, ndiye kuti mungapeze zinthu zosagwedezeka komanso zosalala zomwe zimakhala zosalala, zomwe zimakhala ndi "sandwich". Mkati mwake muli porous, koma mawonekedwe adakali osiyana.

Kupanga kwa PVC yowonjezereka

Kuti Pukutani PVC ndikupanga zomwe mwagwiritsira ntchito, gwiritsani ntchito mizere yopangira zipangizo monga chithunzithunzi, kufa kwa calibrators zofunikira, chipangizo chozizira, cholandira ndi chipangizo chomwe chimakonzekera mankhwalawa. Ngakhale kuti izi zimakhala zovuta mwakuthupi komanso mwakuthupi, ndondomeko yonse yamakono imachitika mumsitolo wawung'ono, woyera komanso wowongoka.

Zida zamakono zopangira zosakaniza ndi granules zimaperekedwa mu matumba apulasitiki. Pa gwero laling'ono la zipangizo, makina osapanga osapanga osapanga omwe amaikidwa mmenemo, madzi akuwonjezeredwa. Choncho, njirayi ikuyamba, chifukwa cha PVC yotupa. Kupanga izo poyang'ana koyamba ndi kophweka. Gawo la polima, limene limasungidwa mu mavotolo kwa maola 24, limagwirizana, limapsa, limafika pamtundu umodzi wa zowonongeka ndipo imadyetsedwa mu gawo lolandira la extruder, lomwe liyenera kupotoza PVC.

Malingana ndi mphamvu ya malonda, extruder ikhoza kukhala ndi piritsi imodzi kapena awiri. Akatswiri amakonda malo omwe ali ndi zikopa ziwiri. Mitengoyi imayendayenda mofanana, choncho kutentha kumakhala kosasinthika kwa nthawi yayitali, yomwe imalola PVC kukhala thovu mofananamo komanso mopanda mphamvu kuti ikwaniritse chiwerengero chofunika mu mankhwala.

Augers amasamutsa pulasitiki misa ku extrusion. Pano (chifukwa cha kupanikizika kwakukulu), n'zotheka kupopera PVC, ndiyeno nkuphwanyidwa kunja kwa extruder kupyola mabowo omwe amapereka mankhwala ndi mawonekedwe. Mafomu opangidwa, mapaipi, mapepala, mafilimu amaperekedwa ku tebulo lolandiridwa, kuchokera komwe amadyetsedwa ku belt conveyor belt ndipo nthawi yomweyo utakhazikika.

Kudula ndi kukongoletsa

Kudula mankhwala a PVC amagwiritsa ntchito macheka ozungulira, wokhala ndi chotsuka chotsuka ndi zidutswa. Kudula zinthu kumapangidwira mofulumira. Kenako, njira yokongoletsa ingagwiritsidwe ntchito pamwamba. Kuti muchite izi, makina opangira makinawa amaphatikizapo makina osindikizira, kusindikiza zithunzi ndi kuikapo chithunzi pa PVC. Zokongoletsera zokongoletsa zimatha kupanga marble chips, plaster, ndi mitundu ina yokongoletsera.

Chofunika ndi chiyani?

Makhalidwe apamwamba kwambiri monga mphamvu, kuunika ndi mawonekedwe abwino, omwe ali ndi thovu PVC. Chithunzi chophatikizidwa m'nkhani ino chikuwonekera momveka bwino pa chitsanzo cha chitoliro. Nkhumbayi imawonekera momveka bwino pazodulidwa, ndipo izi ziribe ngakhale kuti pamwamba pa chipatsocho ndi chowala komanso chosalala.

Kulimbana ndi chikoka cha nyengo zakuthambo ndi zida za nyengo, kugwirizanitsa mankhwala ndi kutentha kwagulitsa kwambiri khomoli kuti ligwiritsidwe ntchito pomanga, malonda, malonda , kutentha ndi mphamvu zamagetsi, mafuta ndi mafuta ndi mafakitale, ndi moyo wa tsiku ndi tsiku.
