PET Bottle Crushing galaw ai kashin kamun lam

PET bottle crishing waling bai jai lang ai jak gaw, PET ntsin htung ni hpe ( mineral hka htung hte lu sha n-gu zawn re ai) ni hpe san seng ai PET flakes ni hku nna, n-gun rawng ai ladat ni hku nna, hkum tsup ai hku galaw shapraw ai ladat langai rai nga ai. Ndai ntsin htung daw ni gaw, polyester kadun ai n-gang ni, shingnip ni, hka htung nnan ni hpe pyi galaw shapraw na matu ahkyak ai raw materials ni rai nga ai.

Ndai galaw shapraw ai line gaw PET bottle circular economy (bottle to bottle cycle) hpe lu la na matu madung arung arai ni rai nga ai.

Hkum tsup ai PET bottle chywi ai hpe bai jai lang ai jak langai hta madung gaw lawu na core process kru lawm ai:

1. Preprocessing - hpaw nna garan ginhka ai

· Puurpose: Shawng nnan e n san seng ai lam ni hpe yeng seng kau nna, hpang na galaw na matu hkyen lajang na matu.

·Arung

·Process: Dai shinggyin tawn da ai nhprang arai ni hpe conveyor belt hte hpaw nna htawt sit ai, dan dawng ai non PET n san seng ai lam ni (dai zawn re ai n-gun n rawng ai arai ni (ga shadawn, magri, glass, PVC gawm, kaga plastic hka htung, laika pa ni zawn re ai) ni hpe lata hte (sh) jak hte galaw ai shingran masa hku nna shaw kau ai.

2. Crushing - Size shayawm ai

· Purpose: Hpang e sung sung san seng hkra galaw na matu hte garan ginhka ai lam a matu, ntsin htung ting hpe kaji kajaw garan kau na matu.

·Equipment: shredder (sh) crish (law malawng gaw nhtu n-gang hte galaw da ai).

·Process: Dai ntsin htung gaw, shinggrup da ai crusher chamber kata de, conveyor belt hku nna shang nna, n-gun ja ai shingnip shingna ni hte maren, n-gun rawng ai daw ni (galaw majaw 12-20mm) hku nna, n-gun rawng ai daw ni hku nna, garan tawn da ai. Hka lim ai aten hta, hka n-gun grai law ai majaw ("hot melt" ngu shamying ai), n-gun n-gun n-rawng ai majaw, plastic hpe hka lim ai hte n-gun n-htum hkra, hka n-gun loi mi hpe hka lim kau na re, dai hka htung nkau mi hpe shawng nnan e kashin kau na matu.

3. Cleaning - N san seng ai arung arai ni hpe yeng seng kau ai gaw, galaw shapraw ai ladat ting a madung rai nga ai, law malawng gaw layer langai hpang langai rawt jat wa ai lam law law hku garan nna galaw ai.

· Pre jasan jaseng ai/hka n-gun hpe jasan jaseng ai lam:

· Purpose: N-gun ja ai label ni hpe n-gun dat hte yeng seng kau na matu, glue, nhpu, hte sau hpraw ni gaw bottle tablet ni hpe bang da ai.

·Equipment: Friction hpe jasan jaseng ai jak ( "scrubbing jak" ngu nna mung shamying ai).

·Process: spiral blade ni a n-gun hte arung arai ni a lapran na shingjawng ai lam hku nna, hka htung, hka, san seng ai lam ni hpe n-gun ja ai hku nna, n-gun ja ai hku htingnut kau ai. N san seng ai hka hpe lawu na sieve hku nna shapraw kau ai.

·Flotation garan ginhka ai lam/hka garan ai lam:

· Puurpose: PET hte n san seng ai lam ni hpe density shai hkat ai lam ni hpe jai lang nna garan ginhka na matu.

·Equipment: flotation hpe jasan jaseng ai tank (sh) hydraulic hka htung.

·Mabyin:

·PET gawm n-gun n-gun ni: hka hta grau law ai density (~1.38 g/cm 3), shanhte gaw hka htung a lawu de lup mat nna screw conveyor kaw na shapraw kau na re.

·Bottle cap material (PP/PE): hka hta npu de n-gun n law ai (~0.90-0.96 g/cm 3), hka ntsa kaw lwi nna, hka lim ai (sh) hka lim ai hku nna garan mat na re.

·Ndai gaw bottle cap hpe bottle hkum hkrang hte garan ginhka ai hta ahkyak ai lahkam langai rai nga ai.

·mup ai alkaline kashin ai:

·purpose: Sau, ngam ai hka, glue zawn re ai organic n san seng ai arung arai ni hpe atsawm sha yeng seng kau na matu, bacteria ana zinli hpe n-gun n rawng hkra galaw na matu hte bacteria hpe sat na matu.

·Equipment: Hot wash tank (sh) katsi ai hka shin tank.

·Process: Bottle slices ni hpe katsi ai alkaline san seng ai hka (galaw majaw NaOH hka, 80℃jan katsi ai ) hta lup da nna, n san seng ai arung arai ni hpe n san seng hkra galaw na matu loi loi hte shinggrup da ai.

·Arut kashin kau ai:

· Purpose: Alkali hte kashin kau da ai ntsin htung n-gang ni hta ngam nga ai jasan jaseng ai tsi hpe atsawm sha kashin kau nna, nhprang arai ni hpe raw kau ya ai.

·Equipment: Multi stage kashin ai tank (sh) drum hka shin jak.

·Process: Reverse flow rinsing ngu ai npawt tara hpe hkap la ai, ngu ai gaw, san seng dik htum hka kata de shang wa nna, hka lwi ai lam gaw, hka hpe makawp maga ai lam hte kaja dik htum san seng ai lam hpe lu la na matu, arung arai rawt jat lam a lam hte nhtan shai nga ai.

4. Hka n-gun - jak n-gun yawm ai

· yaw shada ai lam: Hka lim ai n-gun jai lang ai lam hpe grai shayawm lu na matu, hka lim ai ladat de n shang shi yang, hka htung npu na hka htung ni a ntsa kaw na mai byin ai daram hka law law hpe shaw kau na matu.

·Equipment: Centrifugal hka lim ai jak.

·Process: San seng ngut ai hpang, hka lim ai ntsin htung ni gaw, tsaw ai-}}}} +}speed centrifuge basket de shang wa ai. Centrifugal n-gun kaba a npu hta, hka htung hpe kabai kau nna, hka htung bunghku ntsa na sieve hka htung ni hku nna shapraw kau nna, dai arai a hka n-gun hpe 10% a lawu de shayawm kau lu ai.

5. Hka hpe katsi shangun ai - n-gun ja ai lam

·Purpose: Hka lim ai ntsin htung kata hte ntsa kaw ngam nga ai hka hpe tsep kawp koi kau na matu, hpang na galaw ai lam (sh) shinggyin tawn na matu ra kadawn ai lam ni hpe hkan sa lu na matu (hka n-gun rawng ai lam gaw 1 hta n-pu byin ra ai.

·Equipment: Nbung lwi ai lam hpe katsi shangun ai ladat (law malawng), n-gun rawng ai hka ja ai jak, etc.

·Process: N-gun kaba ai hte n-gun ja ai-}speed nbung gaw, ntsin htung n-gang ni hte hpring tsup ai hku matut mahkai wa nna, hka n-gun hpe yeng seng kau nna, hka n-gun hte n-gun rawng ai gas ni hpe shabyin ya ai. Dai htum mat sai bottle slices ni hpe katsi ai ladat hte katsi shangun nna, dai hpang n-gun dat dat ai.

6. Packaging hte N-gun

·purpose: Hka lim ai hte awu asin byin ai hpe pat shingdang na matu, ngut sai arai hpe hkrak hkra package galaw u.

·Equipment: silo, automatic packaging jak, ton bag packaging jak.

·Process: Katsi mat ai hpang, san seng ai PET ntsin htung ni hpe n-gun ja ai screen jak hte n-gun kaji ni kaw na shinggrup nna, arung arai bin langai mi hta bang da ai. Hpang jahtum, shanhte gaw shi hkum shi n-gun rawng nna, shingkyit kaba (sh) ton bag ni hta bang da ai.

→ n-gun n rawng ai jak → conveyor belt (manual/mechanical garan ai) → crusher (hka n-gun hte) → n-gun n-gun hpe jasan jaseng ai jak → friction garan ginhka ai jak (PP/PE ntsin htung ni hpe garan ai) → high{0}} aten n-gun kaba ai alkali hka shin tank → multi{1}stage rinining tank. → centrifugal hka lim ai jak → nbung lwi ai jak → screen → ngut sai arung arai bin → packaging jak → packaging jak → PET ntsin htung hta hpang jahtum na arung arai hte jai lang ai lam

· Ladat: San seng ai PET Flakes

·Features: Hpraw ai hte san seng ai hkrang, n san seng ai lam ni, n-gun n law ai.

2. Hka shin ai lam: San seng ai ladat gaw hka n san seng ai hka law law hpe shabyin ya ai, hka n san seng ai hka hpe bai jai lang ai (sh) n-gun n rawng ai hku hka shapraw ai lam hpe lu la na matu, hka n-gun hpe jasan jaseng ai ladat (sdimentation, nbung n-gun, biochemical treatment, etc.) hpe gawgap ra ai, n rai yang, lahkawng ngu na n san seng ai lam hpe byin shangun na re.

3. N-gun jai lang ai lam hpe hkang ai: Drying gaw n-gun lang ai lam madung re, dai majaw hka n-gun yawm ai arung arai ni gaw ahkyak ai.

Ndai hkrak hkrak sang lang dan ai gaw PET bottle chywi ai hka shin ai jak hpe atsawm chye na hkra karum ya lu na hpe myit mada ai. Nang hta grau chye mayu ai lam ni hpe tsun dan mayu ai rai yang, anhte hpe bawngban na matu hkum tsang.

1. Hpang jahtum na arung arai ni gaw kaja ai atsam nga ai. PET bottle ni hpe process galaw ai shaloi, hpang jahtum na arung arai ni gaw 1% npu de nga ai.
2. Dai jak gaw, n-gun ja ai, ngang grin ai, n-gun kaba ai etc.
3. SUS304 hpe matut mahkai ai daw ni, 3mm hta jan ai n-gun, daw jau ai lam hpe aten galu galaw ya lu ai.
