Umu ndi momwe mungayeretsere zotulutsira pulasitiki, mukudziwa?

Masiku ano, chifukwa cha ukadaulo wapamwamba, kuyeretsa chotulutsira pulasitiki si vuto lalikulu, koma momwe mungayeretserechotulutsira pulasitikiKuyeretsa bwino komanso kotsika mtengo popanda kuwononga screw ndi mbiya ndi vuto, ndipo lidzakhala vuto ngati litachitika molakwika kapena kuyambitsa vuto lalikulu. Lero, tiyeni tikambirane za momwe tingayeretsere bwino pulasitiki yotulutsa (makamaka screw ndi mbiya) kuti aliyense apindule.

01. Kodi mungatsuke bwanji screw moyenera?

1) Sankhani chipangizo chotenthetsera choyenera

Kugwiritsa ntchito moto kapena moto kuchotsa pulasitiki yomwe yaikidwa pa sikulu ndiyo njira yodziwika bwino komanso yothandiza kwambiri pamakina opangira pulasitiki, koma moto wa acetylene suyenera kugwiritsidwa ntchito kuyeretsa sikulu. Kutentha kwa moto wa acetylene kumatha kufika 3000°C. Kuyeretsa sikulu ndi moto wa acetylene sikungowononga mawonekedwe achitsulo a sikulu, komanso kumakhudza kwambiri kulolerana kwa makina a sikulu.

Ngati lawi la acetylene likhala labuluu losatha pophika gawo lina la sikuru, zikutanthauza kuti kapangidwe ka chitsulo ka gawo ili la sikuru kasintha, zomwe zipangitsa kuti kukana kwa gawoli kuchepe, komanso ngakhale kuchitika kwa gawo lokana kukana ndi matrix. Kuchotsa zitsulo. Kuphatikiza apo, kutentha kwa lawi la acetylene komweko kudzapangitsanso kutentha kwambiri mbali imodzi ya sikuru, zomwe zimapangitsa kuti sikuru ipinde. Ma screw ambiri amapangidwa ndi chitsulo cha 4140.HT chokhala ndi zolekerera zolimba kwambiri, nthawi zambiri mkati mwa 0.03mm.
Kuwongoka kwa sikuru kumakhala mkati mwa 0.01mm. Sikuru ikaphikidwa ndikuziziritsidwa ndi lawi la acetylene, nthawi zambiri zimakhala zovuta kubwerera ku kuwongoka koyambirira. Njira yolondola komanso yothandiza: gwiritsani ntchito blowtorch kuti muyeretse sikuru nthawi yomweyo mukatha kugwiritsa ntchito. Chifukwa sikuru imakhala ndi kutentha panthawi yokonza panthawiyi, kugawa kutentha kwa sikuru kumakhalabe kofanana.

2) Sankhani chotsukira choyenera

Masiku ano, chifukwa cha chuma cha zinthu zomwe zakula kwambiri, pali mitundu yambiri ya zotsukira zomangira (zipangizo zotsukira zomangira) pamsika, zomwe zambiri zimakhala zodula komanso zimakhala ndi zotsatira zosiyana. Kugwiritsa ntchito zotsukira zamalonda kumadalira opanga osiyanasiyana komanso momwe amapangira; makampani opanga pulasitiki amathanso kugwiritsa ntchito ma resin osiyanasiyana ngati zipangizo zotsukira zomangira malinga ndi momwe amapangira, zomwe zingapulumutse ndalama zambiri pa chipangizocho.

3) Sankhani njira yoyenera yoyeretsera

Gawo loyamba poyeretsa sikurufu ndikuzimitsa cholowetsa chakudya, kutanthauza kutseka doko loperekera chakudya pansi pa hopper; kenako chepetsani liwiro la sikurufu kufika pa 15-25r/min, ndikusunga liwiro ili mpaka kusungunuka kwa madzi kutsogolo kwa die kutayike mpaka. Kutentha kwa madera onse otentha a mbiya kuyenera kuyikidwa pa 200°C. Kuyeretsa kumayamba mbiya ikangofika kutentha kumeneku.
Kutengera ndi njira yotulutsira (diye ingafunike kuchotsedwa kuti muchepetse chiopsezo cha kupanikizika kwambiri kumapeto kwa chotulutsira), kuyeretsa kuyenera kuchitika ndi munthu m'modzi: wogwiritsa ntchito amawona liwiro la screw ndi torque kuchokera pa control panel, pamene akuyang'ana extrusion kuti atsimikizire kuti kuthamanga kwa dongosolo sikukwera kwambiri. Pa nthawi yonseyi, liwiro la screw liyenera kusungidwa mkati mwa 20r/min. Mukagwiritsa ntchito diye yotsika mphamvu, musachotse diye kuti muyeretse kaye. Imani nthawi yomweyo chotulutsira ndikuchotsa mutu wa diye pamene chotulutsiracho chasinthidwa kwathunthu kuchoka ku process resin kukhala utomoni woyera, kenako yambitsaninso screw (mkati mwa 10 r/min) kuti utomoni woyera wotsala utuluke.

02. Kodi mungatsuke bwanji bwino mbiya?

Kuyeretsa mbiya kumakhala kosavuta komanso kosavuta kuposa kuyeretsa screw, komanso ndikofunikira kwambiri.
1) Pokonzekera kutsuka mbiya, kutentha kwa mbiya kunayikidwanso pa 200°C.
2) Lumikizani burashi yozungulira yachitsulo ku ndodo yobowolera ndi chobowolera chamagetsi ndikuchiyika ngati chida choyeretsera, kenako kulungani burashi yachitsulo ndi waya wamkuwa.
3) Musanaike chida choyeretsera mu mbiya, ikani stearic acid pang'ono mu mbiya, kapena ikani stearic acid pa waya wa mkuwa wa chida choyeretsera;
4) Pamene waya wamkuwa walowa mu mbiya, yambani kubowola kwamagetsi kuti uzungulire, ndipo nthawi yomweyo upangitse kuti usunthire m'mbuyo ndi mtsogolo mochita kupanga mpaka kuyenda kwa kumbuyo ndi mtsogolo kukhale kopanda mphamvu;
5) Unyolo wa waya wamkuwa ukachotsedwa mu mbiya, gwiritsani ntchito nsalu ya thonje kuti mupukute m'mbiya kuti muchotse utomoni uliwonse woyeretsa kapena zotsalira za mafuta acid; mukapukuta kangapo, mbiyayo imatsukidwa bwino.zomangira ndi migolozakonzeka kukonzedwa kuti zigwiritsidwe ntchito pakupanga kwina!
