Polyvinyl mankhwala enaake (PVC) Zopaka Ufa - Kupanga, Kugwiritsa Ntchito, Kupereka

Pepalali likufotokoza za kukula kwa polyvinyl chloride (PVC) zokutira ufa kunyumba ndi kunja, limayambitsa chilinganizo zofunika, kukonzekera luso ndi ntchito index wa PVC zokutira ufa, ndipo amapanga mawu oyamba ofunikira pakugwiritsa ntchito anti-corrosion ndi kukongoletsa mapaipi achitsulo.

Maulosi

Kupaka ufa ndi mtundu wa 100% ufa wolimba. Zimasiyana ndi zokutira zosungunulira zambiri komanso zosungunulira madzi, osati zosungunulira kapena madzi ngati sing'anga yobalalika, koma mothandizidwa ndi mpweya ngati sing'anga yobalalika. M'mbuyomu decade, maboma a dziko kutulutsa zokutira mafakitale ndi mabizinesi chifukwa cha kuwonongeka kwa chilengedwe kuwonjezera chidwi, analimbikitsa zoletsa ntchito zosungunulira. Pofika kumapeto kwa zaka makumi asanu ndi atatu mu Europe ndi United States mu ❖ kuyanika kupanga, kupanga, ntchito yomanga amaletsedwa kugwiritsa ntchito zosungunulira ndi mpweya, mbali zina za United States komanso mu mawonekedwe a malamulo analengeza zosungunulira ntchito malire lamulo, makonzedwe a ambiri monga 66 makala, ndi Europe ndi United States anaika patsogolo cholinga cha "E zitatu":

(1) Kusintha kwa Ecology
(2) Kupulumutsa Mphamvu
(3) Phindu Lachuma

M'nkhaniyi, zokutira za ufa zakula mofulumira chifukwa cha chikhalidwe chawo chosaipitsa, kugwiritsa ntchito kwambiri zipangizo, ndi ubwino wambiri. Makamaka ku Western Europe ndi North America, kukula kwapachaka kwa zokutira ufa kumafika 10%. Kuphatikiza apo, m'zaka zaposachedwa, China yawonanso chiwonjezeko chodabwitsa pachaka cha 100% cha zokutira ufa.

Polyvinyl kolorayidi (PVC) Powder Coatings amakondedwa kwambiri ndi ogwiritsa ntchito chifukwa cha kukongoletsa kwawo kwapadera komanso nyengo komanso kukana dzimbiri. Panopa, PVC zokutira za ufa Amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana kuphatikiza chitetezo cha chingwe ndi chitoliro chachitsulo, chitoliro cha corrosion resistance, chitoliro cha ngalande za ngalande, mapaipi amafuta amafuta ndi mankhwala, zikwangwani zapamsewu, mizati yowunikira, msewu wachitetezo ndi zina.

Njira Zachitukuko

1.Basic formula ya PVC ufa wophimba

PVC zokutira ufa amapangidwa PVC utomoni monga maziko ndi plasticizer, stabilizer, filler ndi zina. Njira yoyambira ikuwonetsedwa mu Table (White color).

2.Kukonzekera Technology ya PVC ufa wophimba

Njira yokonzekera PVC kupaka ufa, njira yake ikuwonetsedwa mu Chithunzi.

3.Zotsatira za Mayesero a Zochita za Product

Pambuyo pa repekafukufuku ndi chitukuko, kuyesa, ndi kuyerekeza ndi zinthu zochokera kunja, ntchito zina za PVC zokutira ufa pomalizira pake zinafika kapena kupyola kachitidwe ka zinthu zochokera kunja za mtundu womwewo, onani tebulo.

Kugwiritsa ntchito PVC Powder Coated Steel Pipe

PVC filimu yokutira ufa ndi theka-hard thermoplastic state. Poyerekeza ndi polyethylene, kutentha kusungunuka ndi kuwonongeka kwa kutentha kusiyana ndi kochepa, kotero pamene ntchito iyenera kumvetsera kwambiri kutentha kwa kuphika ndi nthawi. Chifukwa cha kusamata bwino kwake, musanamizidwe, nthawi zambiri umafunika kuphimbidwa ndi wosanjikiza wa primer kuti muwonjezere kumatira kwa zokutira.

1.The katundu waukulu wa zokutira

• PVC Zopangira zokutira ufa zimaphatikizapo: zida zodzikongoletsera zamkati ndi nsalu zopanda madzi, akasinja amankhwala, pansi, filimu yophimba, payipi ya dimba ndi kutchinjiriza waya.
• Njira zogwirira ntchito zimatengera kusanganikirana kowuma, kuumba jekeseni, kuumba nkhonya ya extrusion, calendering, ndi fluidized bed kumiza.
• Flame retardant (wowonjezera wowonjezera moto)
• Madzi ndi mankhwala kukana, zabwino kukalamba kukana.

2.Main kumanga njira ndi ntchito zosiyanasiyana

PVC ❖ kuyanika ufa makamaka ntchito zitsulo mauna, ozizira yosungirako okhetsedwa, mipando zitsulo, chitoliro zitsulo ndi zina zotero. Njira yokutira ili makamaka motere:

(1) Chithandizo chisanachitike: chithandizo cha phosphate - kuchotsa dzimbiri, phosphating.
(2) Kupaka koyambira: Dikirani choyambira, mutatha kuyanika, makulidwe a filimu yoyambira ndi 5-10μm,
(3) electrostatic kupopera mbewu mankhwalawa kapena fluidized bedi kuviika.
4. preheating kutentha: 230-290 ℃, 10min, filimu makulidwe: 500um;
Kapena 290 ℃, 5min popanda preheating, filimu makulidwe 200um.

PVC Chitoliro chachitsulo chophimbidwa ndi chothandiza mu petrochemical anti-corrosion, yothandiza mumsewu waukulu wa guardrail, wothandiza pamtengo, patatha zaka zambiri za zotsatira za ntchito zikuwonetsa kuti PVC ❖ kuyanika madzi kukana, mumlengalenga kukana kukalamba ndi zabwino, zambiri likupezeka kwa zaka zoposa 15, kuthetsa vuto la utoto burashi nthawi zambiri, kuyerekeza mabuku ake otsika mtengo, ntchito mankhwala odana dzimbiri, Angagwiritsidwenso ntchito kwa zaka zoposa zisanu, kuti wogwiritsa ntchito athetse vuto la anti-corrosion.
