    ZINTHU ZA MANKHWALA

    Polyvinyl chloride, yomwe nthawi zambiri imafupikitsidwa PVC, ndiye pulasitiki wachitatu wopangidwa kwambiri, pambuyo pa polyethylene ndi polypropylene. PVC imagwiritsidwa ntchito pomanga chifukwa ndiyothandiza kwambiri kuposa zida zachikhalidwe monga mkuwa, chitsulo kapena matabwa mupaipi ndi mbiri. Itha kupangidwa kuti ikhale yofewa komanso yosinthika powonjezera mapulasitiki, omwe amagwiritsidwa ntchito kwambiri kukhala phthalates. Mu mawonekedwe awa, amagwiritsidwanso ntchito mu zovala ndi upholstery, kusungunula chingwe magetsi, mankhwala inflatable ndi ntchito zambiri zimene m'malo mphira.
    Pure polyvinyl chloride ndi yoyera, yolimba yolimba. Sisungunuka mu mowa, koma sungunuka pang'ono mu tetrahydrofuran.
    Peroxide- kapena thiadiazole-CPE yochiritsa imawonetsa kukhazikika kwamafuta mpaka 150 ° C ndipo imalimbana ndi mafuta kwambiri kuposa ma elastomer a nonpolar monga mphira wachilengedwe kapena EPDFM.
    Zamalonda zimakhala zofewa pamene klorini ili ndi 28-38%. Pazinthu zopitilira 45% za klorini, zinthuzo zimafanana ndi polyvinyl chloride. Polyethylene yapamwamba kwambiri ya molekyulu imatulutsa polyethylene ya chlorinated yomwe imakhala ndi kukhuthala kwakukulu komanso kulimba kwamphamvu.

    APPLICATION AREA

    Kutsika mtengo kwa PVC, kukana kwachilengedwe ndi mankhwala komanso kuthekera kogwira ntchito kwapangitsa kuti igwiritsidwe ntchito pazinthu zosiyanasiyana. Amagwiritsidwa ntchito pa mipope ya ngalande ndi ntchito zina zapaipi pomwe mtengo kapena kusatetezeka kwa dzimbiri kumachepetsa kugwiritsa ntchito zitsulo. Ndi kuwonjezera kwa zosintha zosinthika ndi zokhazikika, zakhala zida zodziwika bwino pamafelemu awindo ndi zitseko. Powonjezera mapulasitiki, amatha kukhala osinthika kuti agwiritsidwe ntchito popanga ma cabling ngati cholumikizira waya. Zakhala zikugwiritsidwa ntchito pazinthu zina zambiri.

    Mipope
    Pafupifupi theka la utomoni wa polyvinyl chloride wapadziko lonse lapansi womwe umapangidwa chaka chilichonse umagwiritsidwa ntchito popanga mapaipi opangira ma municipalities ndi mafakitale. Mumsika wogawira madzi amawerengera 66% ya msika ku US, ndipo mu ntchito zapaipi zaukhondo, zimawerengera 75%. Kupepuka kwake, kutsika mtengo, komanso kusamalidwa bwino kumapangitsa kuti ikhale yokongola. Komabe, iyenera kuyikidwa mosamala ndikuyika bedi kuonetsetsa kuti kusweka kwa nthawi yayitali komanso kupitilirabe sikuchitika. Kuonjezera apo, mapaipi a PVC amatha kusakanikirana pamodzi pogwiritsa ntchito simenti zosiyanasiyana zosungunulira, kapena kusakaniza kutentha (njira yophatikizira matako, yofanana ndi kujowina chitoliro cha HDPE), kupanga zolumikizira zokhazikika zomwe sizimatha kutayikira.

    Zingwe zamagetsi
    PVC imagwiritsidwa ntchito ngati kutsekera pazingwe zamagetsi; PVC yogwiritsidwa ntchito pazifukwa izi iyenera kupangidwa ndi pulasitiki.

    Popanda pulasitiki polyvinyl chloride (uPVC) yomanga
    UPVC, yomwe imadziwikanso kuti PVC yolimba, imagwiritsidwa ntchito kwambiri pantchito yomanga ngati zinthu zosasamalidwa bwino, makamaka ku Ireland, United Kingdom, ndi ku United States. Ku USA amadziwika kuti vinyl, kapena vinyl siding. Zinthuzi zimabwera mumitundu yosiyanasiyana ndikumaliza, kuphatikiza chithunzi - kumaliza kwa matabwa, ndipo zimagwiritsidwa ntchito m'malo mwa matabwa opakidwa utoto, makamaka mafelemu a zenera ndi ma sill poika zowulira kawiri m'nyumba zatsopano, kapena m'malo akale onyezimira. mazenera. Ntchito zina zimaphatikizapo fascia, ndi siding kapena weatherboarding. Izi zasintha pafupifupi m'malo mwa chitsulo chotayira popopera mipope ndi ngalande, zomwe zimagwiritsidwa ntchito ngati mapaipi otayira, ma drainpipes, ngalande ndi mipopu. UPVC ilibe ma phthalates, chifukwa amangowonjezeredwa ku PVC yosinthika, komanso ilibe BPA. UPVC imadziwika kuti imalimbana kwambiri ndi mankhwala, kuwala kwa dzuwa, ndi okosijeni kuchokera m'madzi.

    Zovala ndi mipando
    PVC yakhala ikugwiritsidwa ntchito kwambiri pazovala, kupanga zinthu ngati chikopa kapena nthawi zina chifukwa cha PVC. Zovala za PVC ndizofala ku Goth, Punk, fetish zovala ndi mafashoni ena. PVC ndi yotsika mtengo kuposa mphira, chikopa, ndi latex zomwe zimagwiritsidwa ntchito poyerekezera.

    Chisamaliro chamoyo
    Mbali ziwiri zazikuluzikulu zogwiritsira ntchito mankhwala ovomerezeka a PVC ndi zotengera zosinthika ndi machubu: zotengera zomwe zimagwiritsidwa ntchito ngati magazi ndi zigawo zamagazi za mkodzo kapena zinthu za ostomy ndi machubu omwe amagwiritsidwa ntchito potenga magazi ndi kupereka magazi, ma catheters, ma seti a heartlung bypass, hemodialysis set etc. Ku Europe kumwa kwa PVC pazida zamankhwala ndi pafupifupi matani 85.000 chaka chilichonse. Pafupifupi gawo limodzi mwa magawo atatu a zida zamankhwala zapulasitiki zimapangidwa kuchokera ku PVC.

    Pansi
    PVC yokhazikika pansi ndi yotsika mtengo ndipo imagwiritsidwa ntchito m'nyumba zosiyanasiyana zomwe zimaphimba nyumba, zipatala, maofesi, masukulu, ndi zina zotero. Zojambula zovuta ndi 3D zimatheka chifukwa cha zojambula zomwe zingathe kupangidwa zomwe zimatetezedwa ndi wosanjikiza womveka bwino. Chithovu chapakati cha vinyl chimaperekanso kumveka bwino komanso kotetezeka. Malo osalala, olimba a chovala chapamwamba amalepheretsa kupangika kwa dothi komwe kumalepheretsa tizilombo toyambitsa matenda kuswana m'madera omwe amayenera kukhala osabereka, monga zipatala ndi zipatala.

    Mapulogalamu ena
    PVC yakhala ikugwiritsidwa ntchito pazinthu zambiri zogula zocheperako poyerekeza ndi mafakitale ndi malonda omwe tafotokozedwa pamwambapa. Chimodzi mwazinthu zoyambilira za ogula pamsika chinali kupanga zolemba za vinyl. Zitsanzo zaposachedwa kwambiri zikuphatikiza zokutira pakhoma, nyumba zobiriwira, malo osewerera kunyumba, thovu ndi zoseweretsa zina, topper zagalimoto zamagalimoto (ma tarpaulins), matailosi padenga ndi mitundu ina yamkati.

    MMENE MUNGAGULE KWA IFE

    Chemwin ikhoza kupereka ma hydrocarbon ambiri ambiri ndi zosungunulira zamankhwala kwa makasitomala aku mafakitale.Izi zisanachitike, chonde werengani mfundo zotsatirazi zokhuza kuchita bizinesi nafe: 

    1. Chitetezo

    Chitetezo ndicho chofunikira kwambiri chathu. Kuphatikiza pa kupatsa makasitomala chidziwitso chokhudza kugwiritsa ntchito bwino komanso kusamala zachilengedwe kwa zinthu zathu, tadziperekanso kuwonetsetsa kuti chiwopsezo chachitetezo cha ogwira ntchito ndi makontrakitala chikuchepetsedwa kukhala chocheperako komanso chotheka. Choncho, tikufuna kuti kasitomala awonetsetse kuti miyezo yoyenera yotsitsa ndi kusunga chitetezo ikukwaniritsidwa tisanaperekedwe (chonde onani zowonjezera za HSSE pazogulitsa zomwe zili pansipa). Akatswiri athu a HSSE atha kupereka chitsogozo pamiyezo iyi.

    2. Njira yobweretsera

    Makasitomala amatha kuyitanitsa ndikutumiza zinthu kuchokera ku chemwin, kapena atha kulandira zinthu kuchokera kumakampani athu opanga. Njira zoyendera zomwe zilipo zikuphatikiza magalimoto, njanji kapena ma multimodal (mikhalidwe yosiyana imagwira ntchito).

    Pankhani ya zofuna za makasitomala, titha kufotokoza zofunikira za mabwato kapena akasinja ndikugwiritsa ntchito miyezo yapadera yachitetezo / kuwunika ndi zofunikira.

    3. Kuchuluka kwa dongosolo lochepa

    Ngati mumagula zinthu patsamba lathu, kuchuluka kwa madongosolo ocheperako ndi matani 30.

    4.Kulipira

    Njira yolipirira yokhazikika imachotsedwa mwachindunji mkati mwa masiku 30 kuchokera pa invoice.

    5. Zolemba zotumizira

    Malemba otsatirawa amaperekedwa pakubweretsa kulikonse:

    · Bill of Lading, CMR Waybill kapena chikalata china chamayendedwe

    · Satifiketi Yowunikira kapena Yogwirizana (ngati pakufunika)

    · Zolemba zokhudzana ndi HSSE mogwirizana ndi malamulo

    · Zolemba za kasitomu mogwirizana ndi malamulo (ngati pakufunika)
