1. Siponji yolumikizidwa:
Siponji yobwezerezedwanso ndi mtundu wazinthu zobwezerezedwanso zomwe zimachokera kuzinthu za polyurethane. Amapangidwa ndi nyenyeswa za siponji zamakampani zomwe zimaphwanyidwa, kugwedezeka, kusawilitsidwa, chosawilitsidwa ndi kununkhira ndi nthunzi yotentha kwambiri ya guluu ndikukanikizidwa kukhala mawonekedwe. Mtengo wopangira umachepetsedwa kwambiri potengera mtengo wopangira komanso kugwiritsa ntchito. Chifukwa chakuti guluu wambiri umafunika kuwonjezeredwa panthawi yopanga, siponji imanunkhiza kwambiri. Choncho, siponji zobwezerezedwanso akhoza kuwononga thanzi la munthu ndipo ali osavomerezeka.
Zopangira zazikulu zopangira masiponji obwezerezedwanso ndi izi: 1. Mitundu yosiyanasiyana ya masiponji otsika, apakati komanso apamwamba kwambiri, masiponji a laminate, masiponji a nsapato, masiponji ophulika, ndi zina zambiri. ndi processing wakuya wa mankhwala (monga Polyester cartridge sponge, cosmetic sponges) 3. Mitundu yosiyanasiyana ya masiponji, masiponji osayaka moto, masiponji odana ndi malo amodzi, masiponji osefera, masiponji amtundu wamatabwa, masiponji a ngale, masiponji ozungulira 4. Mitundu yosiyanasiyana ya mapilo a siponji (monga monga mapilo a siponji pang'onopang'ono, masiponji athanzi maginito Mitsamiro ndi matiresi osiyanasiyana a siponji) 5. Chalk cha siponji (monga mawotchi, kuloza, kusindikiza, katundu, ndi masiponji ena opaka) ndi zinthu zopangira masiponji 6. Zinthu zosiyanasiyana za siponji (monga zoseweretsa, zapakhomo zinthu) 7. Insulation zinthu zakuthupi 8. PVC, Pe, PP, PS, AES ndi zinthu zina mphira ndi pulasitiki
2. Memory thovu:
Siponji yamtunduwu, yomwe imatchedwanso thonje yobwerera pang'onopang'ono, imabwerera pang'onopang'ono m'mawonekedwe ake oyamba pambuyo popunduka ndi mphamvu yakunja. Ndiko kuti, zinthuzo zimakhala ndi mawonekedwe a viscosity ndi elasticity, zimatengera mphamvu ya kinetic, ndipo zingagwiritsidwe ntchito mobwerezabwereza popanda kupunduka kosatha.
3. Foam EPE :
EPE ngale thonje ndi sanali mtanda ogwirizana obturator dongosolo, amatchedwanso polyethylene thonje thonje. Ndi mtundu watsopano wa zinthu zachilengedwe wochezeka ma CD. Amapangidwa ndi mafuta otsika kwambiri a polyethylene omwe amapangidwa thovu kuti apange thovu lodziyimira palokha. Imakonzedwa mwapadera pogwiritsa ntchito njira yothamanga kwambiri. Ndi kamolekyu kakang'ono kwambiri ndipo kamakhala kolimba kwambiri kuposa masiponji onse. Pambuyo poponderezedwa, thonje la ngale limakonzedwa mwamphamvu mu mawonekedwe a mkanda. Monga momwe amagwiritsidwira ntchito, kupsinjika kwamkati kwa tinthu ta ngale kumatulutsidwa pang'onopang'ono. , ali ndi khalidwe lokhala losavuta kugwiritsa ntchito, kotero kuti zikwama za m'chiuno zomwe zimapangidwa ndi thonje la ngale zimakhala zabwino kwambiri ndipo zimakhala zolimba kwambiri.
Kuwonjezera zinthu zapadera epe ngale thonje, ali ndi katundu odana ndi malo amodzi. Komanso ndi zinthu zachilengedwe wochezeka kuti akhoza zobwezerezedwanso. Amagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, uinjiniya wamakina ndi magetsi, mipando, zida zapakhomo, zida, mphatso zaluso, zinthu zamatabwa, zoumba zamagalasi, kuyika mbali zolondola komanso kutsekereza.
thonje la epe pearl lili ndi ubwino wa madzi ndi umboni wa chinyezi, kugwedezeka, kutsekemera kwa mawu, kuteteza kutentha, pulasitiki yabwino, kulimba kwamphamvu, kubwezeretsanso, kuteteza chilengedwe, ndi kukana mwamphamvu. Panthawi imodzimodziyo, thonje la epe pearl lili ndi ubwino wosunga kutentha, umboni wa chinyezi, anti-friction, anti-kukalamba, ndi kukana kwa dzimbiri. ndi mndandanda wa machitidwe apamwamba ogwiritsira ntchito. Imagonjetsanso zofooka za mphira wamba wa thovu monga brittleness, deformation, ndi kusachira bwino. Imatha kuyamwa ndikumwaza mphamvu yakunja kudzera mukupindika. Imakhala ndi kukana kwamankhwala kwabwino kwambiri. Ndi yabwino m'malo mwa chikhalidwe ma CD zipangizo. Komabe, mtengo wa thonje wa ngale ndi wokwera mtengo, choncho nthawi zambiri umagwiritsidwa ntchito pakati pa mapilo ang'onoang'ono ndi mapilo a lumbar omwe amagwiritsidwa ntchito kawirikawiri komanso owononga makasitomala.
4.PU siponji
PU thovu amapangidwa pogwiritsa ntchito njira zachikhalidwe. PU thovu amapangidwa pochita polima isocyanate ndi polyol.
Zida zopangira thovu la polyurethane zikuphatikizapo isocyanate, polyol, zinthu zochokera ku biologically, zowonjezera maunyolo, maunyolo ogwirizanitsa, zopangira, zowonjezera, ndi zina. Pali zinthu zambiri zomwe zimapita mumtsinje wa polyol, ndipo mitsinje iwiriyi imatchedwa polyurethane systems. Chithovu cha PU chimadziwika ndi mayina osiyanasiyana ku North America ndi Europe. Kutengera ndi mankhwala omwe awonjezeredwa, zolimba zosiyanasiyana ndi zolimba zimalowetsedwa mu thovu la PU. Mitundu iwiri yosiyanasiyana ya chothandizira imagwiritsidwa ntchito mu polyurethanes. Ntchito yayikulu ya chothandizira ndikukulitsa nucleophilicity. Njira za autocatalytic zimachitikanso popanga thovu la PU. PU thovu si cholimba poyerekeza ndi thovu zina.
Kugwiritsa ntchito kwambiri thovu la PU kumakhala pamipando yofewa kwambiri yofewa. Mapanelo olimba a thovu, zosindikizira thovu za microcellular ndi ma gaskets. Kupaka siponji kwa Pu siponji kumagwiritsidwa ntchito makamaka pakuyika, sofa, mipando, zovala ndi mafakitale ena. Packaging siponji ndi chinthu chogwirizana ndi chilengedwe chomwe chili choyenera kuyika mkati mwazinthu kuti chitetezeke pakubisa komanso kuyamwa modabwitsa. Anti-static siponji imateteza zinthu zamagetsi ndi tchipisi ngati masiponji wamba, komanso imakhala ndi anti-static effect, imateteza zinthu zamagetsi ku kuwonongeka kwa magetsi osasunthika. Pu siponji akalowa: kumva wosakhwima, kulimba mtima, sikophweka kupunduka pambuyo ntchito yaitali, ndi kudula mosalala. Kupaka siponji kumagwira ntchito yotchinjiriza, kutsekereza, kutsekereza fumbi, kudzaza, kutsekereza mawu komanso kukonza zinthu m'mafakitale osiyanasiyana. Packaging siponji ndi yoyenera mafoni onse, makompyuta, mphatso zodzikongoletsera, okamba, zoseweretsa, kuyatsa, mawailesi amgalimoto, mabokosi amphatso ndi zinthu zina zowonjezera. Kukula kwazinthu, mtundu, mawonekedwe ndi mtundu zitha kusinthidwa malinga ndi zosowa za makasitomala.
