Kodi zipangizo zopangira pulp molding ndi ziti?

Kuumba zamkati 1: zamkati za nsungwi
Ulusi wa nsungwi ndi chinthu chabwino kwambiri chopangira zinthu zopangira ulusi wa zomera. Ulusi wa nsungwi uli m'gulu la ulusi wautali wapakatikati mpaka wautali, wokhala ndi makhalidwe pakati pa matabwa a coniferous ndi matabwa a masamba otakata. Umapanga makamaka zinthu zapamwamba zogwirira ntchito, ndipo pang'ono zimawonjezeredwa kuzinthu zopangira patebulo.

Zinthu zopangira mapepala opangira mapepala 2: masangweji a masangweji
Ma Bagasse pulp ndi zinthu zabwino kwambiri zopangira zinthu zopangira ma pulp. Kupanga mabokosi a nkhomaliro opangidwa ndi ma pulp ndi zinthu zopangira mbale nthawi zambiri kumagwiritsa ntchito ulusi wa nzimbe. Ma Bagasse pulp amapangidwa kuchokera ku nzimbe kudzera mu pulping ya mankhwala kapena yachilengedwe.

Kuumba zinthu zopangira 3: udzu wa tirigu
Zamkati za udzu wa tirigu, zogawidwa m'magulu awiri: ulusi wa tirigu wa makina, zamkati za udzu wa tirigu wa makina, ndi zamkati za udzu wa tirigu wa mankhwala, makamaka zimapanga zinthu zophikira patebulo.
Udzu wa tirigu uli ndi ulusi waufupi, ndipo pamwamba pa zinthu zopangidwa ndi udzu wa tirigu ndi yosalala komanso yofewa, yokhala ndi kuuma bwino. Zinthuzi ndi zofooka kwambiri koma sizisinthasintha bwino. Zinthu zambiri zopangira tebulo zopangidwa ndi udzu wa tirigu zimatha kugwiritsa ntchito udzu wa tirigu 100% ngati zopangira.

Zipangizo zopangira ma pulp 4: Ma pulp a bango
Ulusi wa pulp wa reed ndi waufupi, ndipo kusalala kwa pamwamba pa zinthu zopangidwa ndi pulp wa reed sikwabwino ngati kwa zinthu zopangidwa ndi pulp wa bagasse, pulp wa nsungwi, ndi tirigu. Kulimba kwake ndi kwapakati ndipo sikwabwino ngati pulp wa bagasse, pulp wa nsungwi, ndi tirigu; Zinthu zopangidwa ndi pulp wa reed zimakhala zofooka ndipo sizisinthasintha bwino; pulp wa reed uli ndi zinthu zambiri zosafunika. Zinthu zambiri zopangidwa ndi pulp walter zingagwiritse ntchito pulp wa reed 100% ngati zopangira.

Zipangizo zopangira ma pulp 5: Ma pulp a matabwa
Ma pulp a nkhuni ndi chinthu chopangira zinthu zopangidwa ndi ma pulp, zomwe zimagwiritsidwa ntchito makamaka popanga zinthu zapamwamba kwambiri zamafakitale.
Masamba a matabwa amagawidwa makamaka m'magulu a matabwa a coniferous ndi matabwa a masamba akuluakulu. Masamba a matabwa omwe amagwiritsidwa ntchito popanga zinthu zopangidwa ndi pulp nthawi zambiri amakhala osakaniza a pulp a matabwa a coniferous ndi matabwa a masamba akulu, chilichonse chimakhala ndi gawo linalake. Masamba a matabwa a coniferous ali ndi ulusi wautali komanso wosalala, pulp ya matabwa oyera, ndi zonyansa zochepa. Ulusi wa pulp ya matabwa olimba ndi wokhuthala komanso wamfupi, ndipo uli ndi zonyansa zambiri. Chogulitsa chomalizidwacho chili ndi mphamvu zochepa, chimakhala chomasuka, chimakhala ndi mphamvu yoyamwa kwambiri, komanso mawonekedwe ambiri.

Kuumba zinthu zopangira 6: Chimanga cha kanjedza
Masamba a kanjedza ndi zinthu zabwino zopangira zinthu zopangira ma pulp. Masamba a kanjedza ndi achilengedwe (mtundu woyamba), makamaka omwe amagwiritsidwa ntchito popanga zinthu zopangira patebulo. Zinthu zopangidwa ndi ma pulp a kanjedza zimakhala ndi mawonekedwe okongola, kuuma bwino, komanso mitundu yachilengedwe ya ulusi wa zomera. Kutalika kwa ulusi wa kanjedza kumafanana ndi ulusi wa ulusi wa tirigu, koma zokolola zake zimakhala zambiri kuposa za ulusi wa tirigu. Ngakhale kuti pali zinthu zambiri zosafunika mu ma pulp a kanjedza, zinthu zosafunikazi ndi ulusi wa zomera, kotero zinthu zopangidwa ndi ma pulp a kanjedza zimawoneka zokongola, zachilengedwe, komanso zosamalira chilengedwe. Ndi chinthu chabwino kwambiri chosamalira chilengedwe.

Zinthu zopangira mapepala 7: Zinyalala za mapepala
Zinthu wamba zopangidwa ndi mapepala otayira zinyalala (zopangidwa ndi ulusi wa zomera) zimatanthauza zinthu zopangidwa ndi chikasu, nyuzipepala, A4, ndi zina zotero m'mabokosi a makatoni, zomwe zimakhala ndi ukhondo wochepa komanso mitengo yotsika. Mathireyi a mazira, thireyi ya zipatso, ndi maphukusi amkati omwe amagwiritsidwa ntchito nthawi zambiri amapangidwa ndi zinthuzi.

Kuumba zinthu zopangira 8: Utoto wa thonje
Zinthu zopangidwa ndi thonje lopangidwa ndi ulusi wa zomera ndi zinthu zopangidwa ndi kukonzedwa pogwiritsa ntchito mapesi a thonje okha ndi minofu yapakati ya mapesi a thonje mutachotsa pamwamba pake. Zinthu zopangidwa ndi ulusi wa thonje zimakhala ndi ulusi wofewa komanso wosalimba, ndipo zimagwiritsidwa ntchito kwambiri popanga mapepala otsika mtengo.

Zipangizo zopangira pulasitiki 9: Zakumwa za mankhwala ophera zinyalala zaulimi ndi nkhalango
Makina opukutira zinyalala za ulimi ndi nkhalango (chomera cha ulusi wa zomera) amapukutira zinthu zopangidwa ndi ulusi, pogwiritsa ntchito njira yopukutira kuti afalitse zinthu zopangira ulusi wa zomera kukhala ulusi pogwiritsa ntchito mphamvu ya makina. Chidutswa chopangidwa ndi njira iyi chimatchedwa makina a makina. Ulusi wa chitsanzo cha makina sunapatukane ndi lignin ndi cellulose, ndipo mphamvu yolumikizira ulusi ndi yofooka. Mankhwala a pulp kapena mankhwala ayenera kugwiritsidwa ntchito pamodzi. Kuchuluka kwa ulusi wa chitsanzo cha makina owonjezeredwa sikuyenera kupitirira 50%, chifukwa zinthu zomwe zili ndi 50% zimakhala zosavuta kutaya chip.

Zipangizo zopangira mapepala 10: Zamkati za mankhwala
Zinthu zopangira kupanga ma pulp pulp (plant fiber molding). Ma pulp a makina a mankhwala amatanthauza ma pulp omwe amachizidwa mankhwala enaake asanapunthidwe, ndipo ma pulp omwe amatuluka amatchedwa ma pulp a makina a mankhwala. Ma pulp a makina a mankhwala nthawi zambiri amakhala ndi zigawo zapamwamba za lignin ndi cellulose, zigawo zochepa za hemicellulose, komanso zokolola zambiri za ma pulp. Mtundu uwu wa ma pulp umagwiritsidwa ntchito kwambiri pazinthu zopangidwa ndi ma pulp apakatikati, zomwe zimakhala ndi mtengo wokwera kuposa ma pulp a makina komanso mtengo wotsika kuposa ma pulp a mankhwala. Kapangidwe kake koyeretsa, kunyowetsa madzi, komanso kusefa madzi ndi kofanana ndi ma pulp a makina.
