Chotulutsira rabara ndi chida chofunikira kwambiri mumakampani opanga rabara komanso chimodzi mwa zida zofunika kwambiri zomwe zimakhudza mtundu wa malonda. Chimagwira ntchito yofunika kwambiri popanga matayala ndi zinthu za rabara. Kupanga kwa zotulutsira rabara zakunja kwakhala ndi chotulutsira cha plug, chotulutsira cha screw type hot feed, chotulutsira wamba chozizira, chotulutsira cha thread cold feed chachikulu ndi chothandizira, chotulutsira cha feed cold feed, chotulutsira cha pin cold feed, chotulutsira cha compound ndi magawo ena. Chotulutsira rabara chimagwiritsidwa ntchito pokanikiza, kusefa ndi kuphimba zinthu za rabara. Kapangidwe kake: Chokuluzira ndi chikwama chamkati zimapangidwa ndi chitsulo cha nitrided, chomwe chimakhala ndi kukana kukalamba bwino komanso kukana dzimbiri.
Kutulutsa screw kwa rabara extruder compound ndi imodzi mwa madera akale aukadaulo wotulutsa, womwe ukhoza kutsatiridwa kuyambira m'zaka za m'ma 1800. Zotulutsa raba zimasiyana kwambiri ndi zotulutsa thermoplastic. Choyamba, kutulutsa raba kumachitika kutentha kotsika (mpaka 130 °C). Kachiwiri, mipiringidzo ya rabara nthawi zambiri imawonjezeredwa ku rabara extrusion (koma nthawi zina, ma pellets amawonjezeredwa), ndipo sasintha gawo kapena kusintha gawo mu dongosolo la screw extruder. Kukhuthala kwakukulu. Izi sizili ngati thermoplastics. Ma thermoplastics ayenera kukonzedwa kutentha kwa 180 ^ -300 °C (kapena kupitirira apo) mu screw extruder, ndipo tinthu tating'onoting'ono tolimba nthawi zambiri timawonjezeredwa ku extruder. Ma pellets akapita patsogolo motsatira screw, chitsime chosungunuka chimapindika.
Zipangizo zotulutsira mphira nthawi zambiri zimagawidwa m'magawo a makina odyetsera otentha ndi makina ozizira. Mu chipangizo chotulutsira mphira chotentha, chosakaniza cha mphira chimatenthedwa ndi makina otseguka, ndipo zingwe za mphira zotenthedwazi zimadulidwa ndikutulutsidwa mosalekeza. Kudyetsa kuchokera ku makina. Mu chipangizo chotulutsira mphira chozizira, mzere wa mphira kutentha kwa chipinda umawonjezeredwa ku chipangizo chotulutsira mphira. Chotulutsira mphira nthawi zambiri chimagawidwa malinga ndi ngati chimagwiritsidwa ntchito potulutsa utsi.
Mtundu wa chotulutsira rabara
Chotulutsira rabara ndi chida chofunikira kwambiri mumakampani opanga rabara komanso chimodzi mwa zida zofunika kwambiri zomwe zimakhudza mtundu wa malonda. Chimagwira ntchito yofunika kwambiri popanga matayala ndi zinthu za rabara. Kupanga kwa zotulutsira rabara zakunja kwakhala ndi chotulutsira cha plug, chotulutsira cha screw type hot feed, chotulutsira wamba cha feed cold, chotulutsira cha thread cold chachikulu komanso chothandizira, chotulutsira cha feed cold feed, chotulutsira cha pin cold feed, chotulutsira cha compound ndi magawo ena.
Zotulutsira mphira zimagawidwa m'magulu awa: mtundu wa plunger, mtundu wa screw, mtundu wamba, mtundu wa chakudya chozizira, mtundu wa pini, mtundu wa compound. M'tsogolomu.
Jinan Power Roller Equipment Co., Ltd ndi kampani yamakono yachinsinsi yomwe ili ndi kafukufuku wa sayansi ndi kupanga. Zinthu zomwe timapereka ndi izi: Womanga Ma Roller Roller, Makina Opukutira Ma Roller Roller, Chopukutira Chakunja cha Cylindrical, Makina Opangira Ma Belt a Emery, Chopukutira Chamkati cha Rubber, Chopukutira Chotseguka, Chida Choyezera Chokha Chokha, Mutu Wopukutira ndi Kuyika Zipangizo.
