Plastic langai sha rai nga ai Screw Extruder
Plastic single screw extruder hpe n-gun ja ai barrel langai mi hta screw galai ai hte hpawng de da ai. Hpa majaw nga yang, asan sha re ai hkrang masa, galaw shapraw ai lam loi ai, galaw shapraw ai atsam kaba ai, manu n law ai majaw, grai lang ai hte hpaji hparat hte seng nna, kungkyang dik htum ai hte masha law law lang ai extruder amyu rai nga ai.
Single screw extruders ni gaw, shawng nnan na npawt nhpang spiral structure kaw nna, screw block, exhaust screw, slotted screw barrel, pin material barrel, hte gawgap ai arung arai ni zawn re ai structural amyu myu de galai shai wa sai. Dai aten hta, shanhte a lamu ga kaji ai majaw, langai sha re ai screw extruder ni gaw, composite processing hte plastic hte gap ai sumla hkrung field ni hta lang ai madung arung arai ni tai wa sai.
Plastic single screw extruder gaw madung hku nna daw masum lawm ai: extrusion system, transmission system, hte katsi ai hte katsi ai ladat.
n hkru n kaja ai ladat
Extrusion system a madung bungli gaw, polymer arung arai ni hpe langai sha re ai hka lim ai de hka lim mat hkra galaw nna, glassy state kaw nna viscous masa de galai shai wa ai lam hpe lu la na matu re. Ndai lam hta, n-gun langai mi hpe gawgap nna, screw hku nna die baw de matut manoi shapraw nna htaw sa wa ai. Dai majaw, extrusion system gaw extrusion galaw ai lam a quality hte output hpe hpaw shabawn ai hta ahkyak ai lit nga ai.
Extrusion system hta madung hku nna gaw, extruder a ahkyak dik ai daw ni rai nga ai, screw, barrel ni lawm ai. Screw gaw extruder a myit masin rai nna, dai arai gaw screw hpe shinggrup ai hku nna barrel kata de sha shamu shamawt lu ai, n-gun hte katsi ai lam nkau mi hpe lu la mai ai.
htaw sa wa ai ladat
Dai transmission system gaw, wan jak mawdaw, shayawm ai jak, hkanghkyi ni hte hpawng de da ai. Extrusion galaw ai aten hta, screw speed gaw ngang grin nna, screw load galai shai ai lam ni hte n bung ai hku nna, langai sha re ai hte n bung ai arung arai ni a quality hpe hkam la lu na matu ra ai. Raitim, masa amyu myu hta, screw gaw, n bung ai arung arai (sh) arung arai ni a hkrang ni hpe shapraw na matu, jak langai mi galai shai lu na matu ra kadawn ai lam hpe hkap la lu na matu, galai shai ai lawan ai lam hpe lu la na matu ra nga ai. Extruder law malawng hta, screw speed galai shai ai lam hpe motor a lawan ai hpe gram lajang ai hku nna lu la nna, transmission system hta mung kaja ai sau htu ai ladat hte lawan ai hku braking galaw ai jak hpe lang da ai.
Hka lum ai hte katsi ai ladat
Extruder a katsi ai hte katsi ai ladat gaw, nbung katsi ai jak hte katsi ai jak langai mi lawm nna, dai gaw n-gun rawng ai extrusion galaw na matu ra kadawn ai masa ni rai nga ai. Hka lum ai jak hte katsi ai jak gaw, polymer arung arai ni hpe hka lim nna plasticize galaw na matu, molding galaw ai aten na nbung laru masa ni gaw, galaw ra ai lam ni hpe hkan sa ra ai.
Dai katsi ai jak hpe extruder a barrel, screw, hte hopper a lawu kaw madung tawn ai. Dai hpe hka katsi ai (sh) nbung katsi ai hku nna, n-gun n-gun hpe shayawm ya lu ai, madung hku nna, kaji kaba a n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun hpe lang nna, nbung katsi ai lam hpe lang mai ai; Extruder kaba ni gaw hka katsi ai (sh) form lahkawng hpe kayau kaya lang ai. Screw cooling gaw madung hku nna hka katsi ai hpe hkap la ai, n-gun ja ai arung arai ni hpe jat ya ai, hka pru ai n-gun hpe ngang grin hkra galaw ya ai, arung arai a hkamja lam hpe grau kaja hkra galaw ya ai. Dai hopper a lawu kaw na katsi ai jak hpe madung hku nna, n-gun ja ai arung arai ni a htawn tsun ai atsam hpe jat ya ai, nbung katsi ai majaw arung arai ni hpe n-gun n rawng hkra pat shingdang ai, arung arai ni hpe pat da ai, lusha jaw sha ai lam hpe hkra machyi shangun ai. 90mm (sh) dai hta jan ai screw diameter lawm ai extruder ni hte tsaw ai{5}}}speed extruder ni a matu, hopper a lawu kaw katsi ai jak hpe bang ra ai.
Ndai set gaw design hta rawt jat wa ai, pru wa ai lam grai law ai, plasticization hta kaja ai hte n-gun lang ai lam n law ai. Involute gear diving gaw nsen n law ai, ngang grin ai bungli galaw ai, hkam sharang ai atsam kaba hte daw jau ai prat galu ai lam ni hpe madun dan ai. Ndai set hpe thermo-plastic ni hpe n-gun ja ai (sh) n-gun ja ai polyvinyl chloride (PVC) hte polystyrene (PE) zawn re ai ni hpe shapraw na matu jai lang mai ai, shing nrai, htap htuk ai karum ningtum jak (moi na ningbaw lawm ai) hte rau, sumla hkrung, pipe, board, braid, belt zawn re ai plastic arung arai amyu myu hpe shapraw lu ai.
