The processing wa zipangizo pulasitiki makamaka ndondomeko kusungunula, kuyenda ndi kuziziritsa mphira particles mu zinthu zomalizidwa atakhala. Ndi njira yotenthetsera kenako kuziziritsa. Ndi njira yosinthira mapulasitiki kuchokera ku tinthu tosiyanasiyana kupita ku mawonekedwe osiyanasiyana. Za kupulasitiki thermoforming makina , ndondomeko yonseyi ikhoza kusinthidwa kuti ikhale yokhazikika popanda kugwiritsa ntchito pamanja, ndipo khalidwe la mankhwala ndilokhazikika! Zotsatirazi zidzalongosola ndondomeko yoyendetsera ntchito kuchokera kumagawo osiyanasiyana.
1. Sungunulani
Chotenthetsera cha chipangizocho chimalola kuti tinthu tating'onoting'ono tisungunuke pang'onopang'ono mukuyenda kwamadzimadzi. Zopangira zosiyanasiyana ndizoyenera kwambiri pakuwongolera kutentha. Kuwonjezeka kwa kutentha kudzafulumizitsa kutuluka kwa zipangizo, zomwe zingathe kuwonjezera mphamvu, koma osati kutsimikizira zokolola. Payenera kukwaniritsidwa bwino lomwe. Kuonjezera apo, zotsatira zabwino ndi makhalidwe a PP pakakhala kuphulika kwakukulu kwa kutentha ndikuti ndi bwino kupanga zopangira kuti ziyende bwino mpaka kufa panthawi yopanga, kuti mupewe kudzaza kosakwanira kapena reflux. Reflux imatanthawuza kuti zopangira zopangira zimayenda mwachangu kuposa momwe zimatulutsira, ndipo pamapeto pake zimawonjezera kuchuluka kwakuyenda bwino, komwe kuli kofanana ndi kusintha kwa MFR. Ndi imodzi mwa njira zomwe zilipo zogwirira ntchito, Komabe, zimayambitsanso kugawa kwa MFR kwachilendo, zomwe zingayambitse kusakhazikika komanso kuwonjezeka kwa chilema. Komabe, chifukwa chakugwiritsa ntchito, zinthu zomalizidwa za PP sizinthu zolongosoka kwambiri, kotero kukhudzika kwake sikwabwino.
2. Tsinde la screw
Zambiri za PP processing zimadalira screw kuti ayendetse fluidity, kotero mapangidwe a screw ali ndi mphamvu yaikulu. The awiri amakhudza linanena bungwe, ndi psinjika chiŵerengero amakhudza kuthamanga mtengo. Zimakhudzanso kutulutsa ndi kumalizidwa kwa mankhwala, kuphatikizapo kusakanikirana kwa zinthu zosiyanasiyana (Color Masterbatch, zowonjezera ndi zosintha). Kuyenda kwa zinthu zopangira kumadalira kwambiri chotenthetsera, koma kukangana ndi kukangana kwa zinthu zopangira kumatulutsanso mphamvu ya kutentha kwamphamvu kuti ifulumizitse madziwo. Choncho, chiŵerengero cha kuponderezana kwa screw ndi chochepa, kutuluka kwake kumakhala kochepa, ndipo liwiro lozungulira liyenera kuwonjezeka, zomwe zimapangitsa kuti pakhale kutentha kwamphamvu kwambiri kuposa wononga ndi chiŵerengero chachikulu cha kuponderezana. Choncho, nthawi zambiri zimanenedwa kuti palibe mbuye pakupanga pulasitiki, ndipo munthu amene amamvetsetsa bwino ntchito ya makinawo ndi mbuye. Kutentha kwa zinthu zopangira sikungotenthetsa, komanso kumaphatikizapo kutentha kwamphamvu komanso nthawi yopumira. Choncho, ili ndi vuto lothandiza. Zochitika zimathandiza kuthetsa mavuto opanga komanso kukonza bwino. Ngati kusakaniza zotsatira za wononga makamaka zabwino, nthawi zina magawo awiri osiyana zomangira kapena biaxial zomangira amapangidwa, ndipo chigawo chilichonse cha mitundu yosiyanasiyana ya zomangira amayikidwa padera kukwaniritsa zosiyanasiyana kusanganikirana zotsatira.
3. Ifa kapena kufa mutu
Kukonzanso kwa pulasitiki kumadalira nkhungu kapena mutu wakufa. The jekeseni akamaumba chotsirizidwa ndi mbali zitatu, ndipo nkhungu ndi zovuta. Vuto la kuchepa liyenera kuganiziridwa. Zogulitsa zina ndi ndege, mizere ndi singano mosalekeza mankhwala amafa. Ngati ali mawonekedwe apadera, amawaika ngati mawonekedwe apadera. Chisamaliro chiyenera kuperekedwa ku vuto la kuzizira nthawi yomweyo ndi kukula kwake. Makina ambiri apulasitiki amapangidwa ngati ma syringe. Mphamvu ya extrusion yoyendetsedwa ndi wononga imayambitsa kupanikizika kwakukulu panyumba yaying'ono ndikuwongolera magwiridwe antchito. Pamene mutu wakufa umapangidwira ngati ndege, momwe mungapangire zipangizo zomwe zimagawidwa mofanana pamtunda wonse, mapangidwe a hanger amafa mutu ndi ofunika kwambiri. Samalani ndi mwayi extrusion kuonjezera mpope gill nsomba ndi kukhazikika kotunga kwa zipangizo.
4. Kuziziritsa
Kuwonjezera pa kuthira zipangizo mu chipata cha sprue, nkhungu ya jekeseni ilinso ndi mapangidwe a zipangizo zoziziritsira muzitsulo zoziziritsira. Kuumba kwa Extrusion kumadalira njira yamadzi yozizira mu chogudubuza kuti ikwaniritse kuziziritsa. Kuonjezera apo, palinso mipeni ya mpweya, madzi ozizira omwe amathiridwa mwachindunji pa thumba lowombera, kuwomba kopanda phokoso ndi njira zina zoziziritsira.
5. Wonjezerani
Kukonzanso kwazinthu zomalizidwa ndi kukulitsa kumawonjezera zotsatira zake. Mwachitsanzo, kuthamanga kosiyana kwa lamba wonyamula katundu woyendetsedwa ndi odzigudubuza kutsogolo ndi kumbuyo kumayambitsa kukulitsa. Mphamvu yowonjezereka ya gawo lowonjezera la mankhwala omalizidwa amalimbikitsidwa, zomwe sizili zophweka kung'amba, koma ndizosavuta kung'amba mozungulira. Kugawa kwa kulemera kwa mamolekyu kudzakhudzanso zotsatira zowonjezera pakupanga mofulumira kwambiri. Zogulitsa zonse zotulutsidwa, kuphatikiza ulusi, zimakhala ndi zowonjezera zosafanana. Vacuum ndi mpweya woponderezedwa ukhoza kuwonedwa ngati njira ina yowonjezera.
6. Funani
Zopangira zilizonse zimakhala ndi vuto la shrinkage, lomwe limayamba chifukwa cha kupsinjika kwamkati panthawi yakukula kwamafuta, kuzizira kozizira ndi crystallization. Nthawi zambiri, kufutukuka kwa kutentha ndi kuzizira kozizira ndikosavuta kugonjetsa, zomwe zingatheke ndikutalikitsa nthawi yozizirira pokonza ndikusunga kupanikizika mosalekeza. Zopangira za crystalline nthawi zambiri zimakhala ndi kusiyana kwakukulu kwa shrinkage kuposa zopangira zopanda makristalo, pafupifupi 16% ya PP, koma pafupifupi 4% ya ABS, yomwe ndi yosiyana kwambiri. Gawoli liyenera kugonjetsedwa pa nkhungu, kapena zowonjezera kuti muchepetse kuchuluka kwa shrinkage nthawi zambiri zimawonjezeredwa, LDPE nthawi zambiri imawonjezeredwa ku mbale ya extrusion kuti athetse vuto la khosi.
Pulasitiki thermoforming makina imagwira ntchito pafupifupi thermoplastics yonse. M'zaka zaposachedwa, makina apulasitiki opangira thermoforming adagwiritsidwanso ntchito bwino kupanga mapulasitiki a thermosetting. Kuzungulira kuzungulira kwa thepulasitiki thermoforming makina ndi lalifupi (masekondi pang'ono mpaka mphindi zingapo), ndipo likhoza kupanga zisankho ndi mawonekedwe ovuta, kukula kolondola komanso nthawi imodzi. Makina a GTMSMART thermoforming amaphatikizansoPulasitiki Thermoforming Machine,Makina a Cup Thermoforming,Makina Opangira Pulasitiki,Pulasitiki Flower Pot Thermoforming Machine.
GTMSMART perekani makina apamwamba kwambiri pamtengo wabwino kwambiri womwe ungakwaniritse zosowa zanu zopanga zambiri. Onani mndandanda wazinthu zathu ndipo mupeza zosankha zambiri zapamwamba zomwe zimagwirizana ndi zomwe mukufuna.
