Jekeseni akamaumba chitoliro zovekera nthawi zambiri kukumana chodabwitsa kuti nkhungu sangathe kudzazidwa ndi ndondomeko processing.Pamene makina opangira jekeseni atangoyamba kugwira ntchito, chifukwa kutentha kwa nkhungu kunali kochepa kwambiri, kutaya kwa kutentha kwa zinthu zosungunuka za PVC kunali kwakukulu, zomwe zinali zosavuta kulimba koyambirira, ndi kukana kwa nkhungu kunali kwakukulu, ndipo zinthuzo sizikanatha. mudzaze patsekeke.Izi ndi zachilendo komanso zosakhalitsa.Zizimiririka zokha pambuyo jekeseni mosalekeza wa nkhungu digito.Ngati nkhunguyo siyingadzazidwe nthawi zonse, lingalirani izi ndikusintha koyenera:

Mabubu pa chitoliro

Kutentha kwa thovu kumapangidwa chifukwa cha kutentha kwakukulu.Kutentha kwapamwamba kwambiri kumayambitsa thovu muzowonongeka muzopangira, komanso kuwola pang'onoZithunzi za PVCzinthu zopangira thovu, zomwe zimadziwika kuti ma thovu otentha.Moyenera sinthani liwiro la jekeseni

Kuthamanga kwa jakisoni ndikothamanga kwambiri.Chifukwa kuumba ndondomeko yaPVC-UZopangira jekeseni ziyenera kukhala ndi liwiro lotsika la jakisoni komanso kuthamanga kwambiri kwa jakisoni.Kuthamanga kwa jekeseni kungasinthidwe moyenera.

Ngati chipatacho ndi chaching'ono kwambiri kapena gawo lolowera njira ndilaling'ono kwambiri, kukana kwazinthu zoyenda ndikwambiri.Chipata ndi gawo lothamanga likhoza kukulitsidwa kuti muchepetse kusungunuka kwa kusungunuka.

Zomwe zimakhala ndi chinyezi kapena zinthu zina zosasunthika muzopangira ndizokwera kwambiri kapena zopangira zasungidwa kwa nthawi yayitali, ndipo chinyezi chamlengalenga chimatengedwa.Kuwongolera mosamalitsa zomwe zimasokonekera muzinthu zopangira pogula zopangira, ndipo zida zopangira ndi zothandizira siziyenera kusungidwa kwa nthawi yayitali kapena madera okhala ndi chinyezi chambiri mumlengalenga.

Zowoneka bwino za mankhwala

Kuwala kwapamwamba kwa zinthu zopangidwa ndi jekeseni wa PVC kumagwirizana kwambiri ndi kusungunuka kwa zinthu za PVC.Chifukwa chake, kuwongolera kuchuluka kwa zinthu zakuthupi ndi njira yofunika kwambiri yopititsira patsogolo zinthu.Chifukwa kutentha kwa zinthu zosungunuka kumakhala kochepa komanso kusungunuka kwa zinthuzo ndi kosauka, kutentha kwa zinthuzo kumawonjezeka moyenerera, makamaka kutentha pamphuno.

Njirayi ndi yosamveka, kotero kuti pulasitiki yazinthuzo siili m'malo kapena chodzaza ndi chochuluka, chilinganizocho chiyenera kusinthidwa, ndipo khalidwe la plasticization ndi fluidity ya zinthuzo ziyenera kusinthidwa kupyolera mwa kuphatikiza koyenera kwa zothandizira kukonza, ndi kuchuluka kwa fillers kuyenera kuyendetsedwa.

Osakwanira nkhungu kuzirala, kusintha nkhungu kuzirala kwenikweni.Ngati kukula kwa chipata ndi chaching'ono kwambiri kapena gawo lothamanga ndilochepa kwambiri, kukana kumakhala kwakukulu kwambiri.Mutha kuwonjezera gawo lothamanga moyenera, kuwonjezera chipata, ndikuchepetsa kukana.

Zomwe zimakhala ndi chinyezi kapena zowonongeka zina muzopangira ndizokwera kwambiri.Zopangira zimatha kuuma kwathunthu, kapena chinyontho kapena mavuvu amatha kuchotsedwa kudzera muzinthuzo.Ngati utsiwo uli wosauka, chopondera chikhoza kuwonjezeredwa kapena malo olowera pachipata angasinthidwe.

Pali mizere yowonekera yowotcherera

Kutentha kwa zinthu zosungunuka kumakhala kochepa, ndipo kutentha kwa mbiya kumatha kuwonjezereka moyenera, makamaka kutentha kwa nozzle kuyenera kuwonjezeka.Ngati kuthamanga kwa jakisoni kapena kuthamanga kwa jakisoni kuli kochepa, kuthamanga kwa jakisoni kapena kuthamanga kwa jakisoni kumatha kukulitsidwa moyenera.

Ngati kutentha kwa nkhungu kuli kochepa, kutentha kwa nkhungu kungathe kuwonjezeka moyenerera.Ngati chipatacho ndi chaching'ono kwambiri kapena gawo la mtanda la wothamanga ndilochepa kwambiri, mukhoza kuwonjezera wothamanga kapena kukulitsa chipata moyenerera.

Kutulutsa kosakwanira kwa nkhungu, kumawonjezera magwiridwe antchito a nkhungu, kuwonjezera ma groove otulutsa.Voliyumu ya chitsime chozizira ndi yaying'ono kwambiri, kotero kuchuluka kwa chitsime chozizira kumatha kukulitsidwa moyenera.

Kuchuluka kwa lubricant ndi stabilizer mu chilinganizo ndi mochuluka, ndipo kuchuluka kwawo kungasinthidwe.Kuyika kwa patsekeke sikuli kwanzeru ndipo mawonekedwe ake amatha kusinthidwa.

Zizindikiro zozama kwambiri

Kuthamanga kwa jakisoni wa Gaoan ndikotsika, kotero kuthamanga kwa jakisoni kumatha kukulitsidwa moyenera.Kupanikizika kokhazikika kogwira nthawi sikokwanira, mutha kuwonjezera nthawi yogwira ntchito moyenera.

Nthawi yoziziritsa yokhazikitsidwa sikokwanira, mutha kuwonjezera nthawi yozizira moyenera.Ngati kuchuluka kwa sol sikukwanira, onjezerani kuchuluka kwa sol moyenera.

Mayendedwe amadzi a nkhungu ndi osagwirizana, ndipo dera lozizira likhoza kusinthidwa kuti mbali zonse za nkhungu zizizizira mofanana.Kukula kwapangidwe kachitidwe ka nkhungu gating ndi kakang'ono kwambiri, ndipo chipata chikhoza kukulitsidwa kapena chachikulu, nthambi, ndi miyeso yothamanga yodutsamo imatha kukulitsidwa.

Zovuta kupanga

Kuvuta kugwetsa kumachitika chifukwa cha nkhungu ndi njira yosayenera, koma nthawi zambiri imayamba chifukwa cha kugwetsa kosayenera kwa nkhungu.Pali makina opangira mbedza pamakina ogwetsera, omwe amayang'anira kutulutsa zinthu zoziziritsa kukhosi, wothamanga ndi pachipata: njira yotulutsa imagwiritsa ntchito ndodo ya ejector kapena mbale yapamwamba kuti itulutse chinthucho mu nkhungu yosunthika.Ngati ngodya yowongoka sikokwanira, kukonza kumakhala kovuta.Payenera kukhala kuthamanga kwa mpweya wokwanira panthawi yotulutsa pneumatic ndi kugwetsa., Apo ayi padzakhala zovuta pakugwetsa.Komanso, pachimake kukoka chipangizo cha olekanitsa pamwamba, ulusi pachimake kukoka chipangizo, etc. zonse mbali zofunika mu dongosolo demolding, ndi zosayenera kamangidwe adzachititsa movutikira demolding.Choncho, pakupanga nkhungu, njira yowonongeka ndi gawo lomwe liyenera kuperekedwa.Pankhani yowongolera njira, kutentha kwambiri, chakudya chambiri, kuthamanga kwambiri kwa jakisoni, komanso nthawi yayitali yozizirira zimabweretsa zovuta kutsitsa.

Mwachidule, mavuto osiyanasiyana khalidwe zidzachitika processing waPVC-Umankhwala opangidwa ndi jekeseni, koma zifukwa zamavutowa ndi zida, zisankho, mafomu, ndi njira.Malingana ngati pali zida zonse ndi nkhungu, njira zoyenera ndi ndondomeko, mavuto amatha kupewedwa.Koma pakupanga kwenikweni, mavutowa nthawi zambiri amawonekera, kapena amawonekera popanda kudziwa zifukwa ndi zothetsera, malingana ndi kudzikundikira kwa zochitika.Wolemera ntchito zinachitikira ndi chimodzi mwa zikhalidwe kuonetsetsa wangwiro mankhwala.
