Kuponyera Mpira wa Polyurethane
Kuponyera mphira wa polyurethane ndi njira yotchuka yogwiritsidwa ntchito ndi opanga kupanga zinthu zolimba komanso zosinthika. Njirayi imaphatikizapo kusakaniza zigawo ziwiri zamadzimadzi, polyol ndi isocyanate, pamodzi moyenerera. Kusakaniza kumeneku kumatsanuliridwa mu nkhungu kapena pabowo komwe kumauma ndikuchira pakapita nthawi.
Pofuna kuwonetsetsa kuti ntchitoyo ikuyenda bwino, ndikofunika kutsatira njira zodzitetezera monga kuvala magolovesi oteteza ndi zovala za m'maso, kugwira ntchito pamalo opumira mpweya wabwino, komanso kutsatira malangizo opangira mankhwala. Chikombolecho chiyeneranso kukonzedwa pogwiritsa ntchito chotulutsa kuti chiteteze mphira wochiritsidwa kuti asamamatire pamwamba.
Mukathiridwa mu nkhungu, chisakanizocho chidzayamba kukula pang'ono pamene chikuchira. Pambuyo pa maola angapo kapena masiku malingana ndi zofunikira za mankhwala, mphira woponyedwa amatha kuchotsedwa mu nkhungu ndikumalizidwa ndi zowonjezera monga kudula zinthu zowonjezera kapena kuwonjezera mawonekedwe. Ponseponse, mphira woponyera polyurethane umapatsa opanga njira yabwino yopangira zinthu zapamwamba kwambiri zokhala ndi milingo yosiyanasiyana ya kuuma komanso kusinthasintha kwamafakitale osiyanasiyana kuphatikiza zida zamagalimoto, katundu wogula, ndi zida zamankhwala.
Ngati mukupeza kampani yopanga polyurethane service, Chonde Lumikizanani nafe khalani omasuka.
Zida ndi Zopereka
Zikafika pakuponyera mphira wa polyurethane, zida ndi zinthu zomwe mumagwiritsa ntchito ndizofunikira kuti mukwaniritse bwino. Choyamba, mudzafunika nkhungu yopangidwa kuchokera ku silikoni kapena zinthu zina zoyenera kuti mugwire madzi a polyurethane. Kuphatikiza apo, mufunika zotulutsa monga petroleum jelly kapena spray-on solutions zomwe zimalepheretsa mphira wochiritsidwa kuti asamamatire ku nkhungu.
Chotsatira chofunikira kwambiri ndi polyurethane yokha, yomwe imabwera m'magawo awiri: utomoni ndi chowumitsa. Ndikofunikira kuyeza zigawo izi molondola kuti muchiritse nthawi yabwino komanso mphamvu ya chinthu chomaliza. Kutengera kuuma kwanu kapena kusinthasintha komwe mukufuna, mutha kusankha kuchokera kumitundu yosiyanasiyana ya polyurethane yokhala ndi ma resin-to-hardener osiyanasiyana.
Zida zina zofunika zimaphatikizapo makapu osakaniza, ndodo zogwedeza, magolovesi, ndi magalasi otetezera chifukwa kugwira ntchito ya polyurethane yamadzimadzi kumafuna kusamala kwambiri kuti musawononge khungu kapena kuwonongeka kwa maso. Zida zonsezi zikapezeka ndikukhazikitsidwa moyenera molingana ndi malangizo a wopanga, ndi nthawi yoti muyambe kuponya!
Kukonzekera Nkhungu
Musanaponye mphira wa polyurethane, kukonzekera nkhungu ndi gawo lofunikira lomwe silingalumphe. Choyamba, nkhungu iyenera kukhala yoyera komanso yopanda zinyalala kapena dothi. Izi zikhoza kutheka mwa kutsuka pamwamba pa nkhungu ndi burashi yofewa kuti muchotse particles zotayirira.
Chotsatira, ndikofunika kugwiritsa ntchito wothandizira kumasula ku nkhungu pamwamba. Wotulutsa amalepheretsa mphira wa polyurethane kuti asamamatire ku nkhungu ndikuwonetsetsa kumasulidwa kosalala kamodzi kokha. Pali mitundu yosiyanasiyana ya zotulutsa zomwe zimapezeka pamsika, monga zopopera kapena zakumwa, ndipo kusankha imodzi zimatengera zinthu zosiyanasiyana monga mtundu wa utomoni ndi nthawi yochiza.
Pomaliza, tikulimbikitsidwa kuwonjezera njira zolowera mpweya m'malo omwe matumba a mpweya amatha kupanga pochiritsa. Makanemawa amalola kuti mpweya wotsekeredwa utuluke panthawi yoponyedwa komanso kupewa kuwonongeka kwa chinthu chomaliza. Njira zolowera mpweya zimatha kupangidwa pobowola mabowo ang'onoang'ono m'malo omwe mpweya ukhoza kutsekeka, monga ngodya kapena malo otchinga.
Ponseponse, kukonzekera bwino nkhungu yanu musanaponye mphira wa polyurethane ndikofunikira kuti mupeze zotsatira zapamwamba ndikuwonetsetsa kuti nkhungu zanu zizikhala nthawi yayitali popanda kuwonongeka.
Kusakaniza Rubber Compound
Kuti mupange mphira wa polyurethane, muyenera kusakaniza magawo awiri amadzimadzi. Gawo loyamba ndi polyol kapena resin, yomwe imapereka msana wa polima. Gawo lachiwiri ndi isocyanate kapena hardener yomwe imagwirizana ndi polyol kupanga polima wolimba. Kusakaniza zigawo ziwirizi pamodzi kumayambitsa kusintha kwa mankhwala komwe kumasintha madzi osakaniza kukhala zotanuka komanso zolimba.
Njira yosakaniza iyenera kukhala yolondola chifukwa imatsimikizira zomwe zimapangidwira. Kusakaniza kosakwanira kungasiye matumba osakanizidwa muzojambula zanu zomaliza, zomwe zimabweretsa kusagwirizana kwa kuuma, mtundu, ndi maonekedwe. Zitha kupangitsanso kung'ambika ndi kung'ambika pazida chifukwa cha kugawanika kwapang'onopang'ono panthawi yonse yomwe mukuponya.
Kuti mukwaniritse zotsatira zabwino pakusakaniza, ndikofunikira kuti mugwiritse ntchito miyeso yolondola pazigawo zonse ziwiri zapawiri yanu, tsatirani malangizo a wopanga mosamala ndikugwiritsa ntchito zida zoyenera zotetezera monga magolovesi, magalasi ndi zopumira pogwira mankhwalawa. Mukasakaniza mankhwala anu bwino, tsanulirani muzitsulo zomwe mwasankha mwamsanga asanayambe kuchiritsa kapena kuumitsa - izi zimatsimikizira kufanana pamagulu anu onse.
Kuthira & Kuchiritsa
Kuthira ndi kuchiritsa ndi njira zofunika pakuponya mphira wa polyurethane. Musanayambe ndondomekoyi, ndikofunika kukonzekera nkhungu poyeretsa ndi kugwiritsa ntchito wothandizira kumasula. Chikombole chikakonzeka, ndi nthawi yosakaniza mphira wa polyurethane malinga ndi malangizo a wopanga. Chiŵerengero cha magawo A ndi B chiyenera kukhala cholondola kuti zitsimikizidwe kuchiritsidwa koyenera.
Kenaka, tsanulirani pang'onopang'ono mphira wosakanikirana wa polyurethane mu nkhungu. Ndikofunika kupewa kuyambitsa thovu la mpweya panthawiyi pothira pang'onopang'ono ndikugwiritsa ntchito kamtsinje kakang'ono kakusakaniza. Mukathira, kanizani pang'onopang'ono kapena kunjenjemera nkhungu kuti muthandizire kuti tinthu tating'ono ta mpweya totsala tiwuke pamwamba.
Kuchiritsa kumatha kutenga kulikonse kuchokera kwa maola angapo mpaka masiku angapo kutengera zinthu monga kutentha, chinyezi, ndi makulidwe ake. Ndikofunika kuti musasokoneze kapena kuchotsa kuponyera mpaka kuchira chifukwa kuchotsa msanga kungayambitse kuwonongeka kapena kung'ambika kwa zinthuzo. Mukachira, chotsani mosamala chinthu chatsopano cha rabara cha polyurethane mu nkhungu yake kuti mugwiritsenso ntchito kapena kumaliza.
Zokwanira Zomaliza
Mukathira chisakanizo cha polyurethane mu nkhungu, ndi nthawi yoti muyang'ane pazomwe zimamaliza zomwe zingapangitse kuti chinthu chanu chomaliza chiwale. Chimodzi mwazinthu zofunika kwambiri ndikuchotsa mosamalitsa thovu lililonse la mpweya lomwe lingakhalepo panthawi yoponya. Izi zikhoza kuchitika pogogoda pang'onopang'ono kapena kugwedeza nkhungu kuti zilimbikitse mpweya uliwonse wotsekedwa kuti ukwere pamwamba ndi pop.
Mukatsimikizira kuti mavuvu onse a mpweya achotsedwa, ndi nthawi yoti mulole mankhwala anu a rabara a polyurethane. Kuchiritsa kumatenga maola angapo ndipo sikuyenera kuchitidwa mopupuluma. Ndikofunikira kuti mulole oponya anu azikhala osasokonezeka mpaka atachira musanayese kuchotsa mu nkhungu.
Pomaliza, chiwalo chanu chikachira, mutha kuyamba kuchichotsa mu nkhungu. Izi ziyenera kuchitidwa mosamala kuti musawononge kapena kusokoneza mankhwala anu omaliza mwanjira iliyonse. Ndi kuleza mtima pang'ono komanso kusamala mwatsatanetsatane panthawi yomalizayi, mudzakhala ndi chidutswa chopangidwa mwaluso chopangidwa kuchokera ku rabara ya polyurethane!
Kutsiliza
Pomaliza, kuponyera mphira wa polyurethane kumafuna kukonzekera mosamala komanso kusamala mwatsatanetsatane. Musanayambe kuponya, ndikofunika kuyeza bwino ndikusakaniza zigawo za polyurethane resin malinga ndi malangizo a wopanga. Izi zidzatsimikizira kuti chomalizacho chili ndi katundu wofunidwa ndi makhalidwe.
Utomoni ukasakanizidwa, uyenera kutsanuliridwa mu nkhungu yomwe yakonzedwa bwino ndi wothandizira kumasulidwa. Kenako nkhunguyo iyenera kusiyidwa mosasokoneza kwa maola angapo kuti utomoni uchiritse kwathunthu. Pambuyo kuchiritsa, chilichonse chowonjezera chimatha kudulidwa ndipo chomalizidwacho chikhoza kuchotsedwa mu nkhungu.
Ponseponse, kuponyera mphira wa polyurethane kungakhale njira yovuta koma yopindulitsa kwa iwo omwe ali okonzeka kuyika nthawi ndi kuyesetsa kofunikira. Ndi njira yoyenera komanso kusamala mwatsatanetsatane, ndizotheka kupanga ma castings apamwamba kwambiri omwe amakwaniritsa zosowa zanu ndi zomwe mukufuna.
