Njira ya Rotomolding - Tengani mwachitsanzo kupanga bokosi lazakudya

Uku ndiye kupanga bizinesi yopanga bokosi lazakudya, mutha kuloza kuti muphunzire chidziwitso choyenera charotomolding.

Rotomolding ndi njira yatsopano komanso yapamwamba yopangira pulasitiki, yomwe imadziwika ndi:

1, yoyenera kukonzedwazazikulu dzenje mankhwala, mongathanki yamadzi, thanki yamafuta, zida zazikulu zosangalatsa, kudzipatula khoma, etc.

2,Mtengo wokonza ndi wotsika, makamaka mtengo wa nkhungu ndi 1/3 yokha ya nkhungu ya jakisoni. Kuipa kwake ndi kufunikira kwakukulu kwa zida zopangira, ndipo kulondola kwazinthu zomalizidwa ndizovuta poyerekeza ndi jekeseni.

Kapangidwe kake ndi motere:

一,Kukonzekera kwa zipangizo

(一) Zofunika zakuthupi zarotomolding kupanga

1.melting index nthawi zambiri saposa 5.0g/10min.

2.ufa particles 30 ~ 60 mauna (zozungulira particles sangakhale ndi chiwerengero chachikulu cha mchira ndi prisms, flake particles).

3.kuuma.

(二) Zofunikira pazida zopangirakupanga mapulasitiki

LLDPE yokhala ndi chingwe chimodzi ndiyovuta kutsimikizira zofunikira zazinthu (monga mabokosi osungira nkhondo opangidwa ndi kampani yathu), kotero zida zophatikizika (zomwe zimadziwikanso kuti kusinthidwa kwa pulasitiki) zimagwiritsidwa ntchito, monga 7042 ndi UR644 zida zokhala ndi madzi abwino. koma mphamvu zosakwanira. Chifukwa chake kuti mutsimikizire mtundu wazinthu zenizeni, 7042, 6090, 500S kapena UR644, A760. Enieni mankhwala chilinganizo zopangira analandira pambuyo makumi mamiliyoni mayesero asayansi, chinsinsi, ndi patent, aliyense sangasinthe chilinganizo popanda kuyezetsa.

A limodzi enieni mankhwala ayeneranso kuwonjezeredwa malinga ndi ntchito ya mankhwala, ena mbuye, antioxidants, monga kupanga mtundu kujowina mpukutu pulasitiki kalasi mbuye. Mankhwalawa amagwiritsidwa ntchito panja kwa nthawi yaitali, kuwonjezera ma antioxidants, kupanga zinthu zowononga moto, anti-aging agents, olimbikitsa ndi zina zotero.

(三) njira yeniyeni yaukadaulo

1. Malinga ndi makonzedwe a mtsogoleri, mitundu yonse ya zipangizo ndi ma accelerators olembedwa mu ndondomeko ya mankhwala amaikidwa mu chosakanizira ndi ogwira ntchito mwapadera, ndipo chosakanizacho chimasakanizidwa kumayambiriro kwa chosakaniza. Nthawi yosakaniza ndi> Mphindi 10 (chosakaniza chimagawidwa kukhala chosakanizira wamba ndi chosakanizira chothamanga kwambiri, ndipo tikulimbikitsidwa kugwiritsa ntchito chosakaniza chothamanga kwambiri ngati thumba likuloleza. zopangira, zomwe ziyenera kugwiritsidwa ntchito ndi zida zoyenerera.

2, extrusion granulation machine operator ndi hand disk motor pulley, makina amatha kuthamanga mosavuta, zinthuzo zitasakaniza batch mu makina opangira granulation, batani lamoto ndi zina zotero. Pambuyo pa ammeter yamagalimoto ikukwera, tsekani batani lotentha ndikusintha kutentha kwa malo otentha. kampani yanga anagula makina granulating anawagawa m'madera anayi Kutentha, kuchokera hopper patsogolo motsatira: dera lililonse, zambiri 150 ℃. Malo achiwiri ndi 180 ℃. Pambuyo pomaliza gawo lachitatu 180 ℃. Mphuno yake ndi 190 ℃.

Mzere wazinthu zomwe zatulutsidwa zikakhazikika ndi thanki yamadzi, imayikidwa mu granulator ndipo chosinthira mphamvu cha granulator chimatsekedwa. Makina opukutira amangokokera pamzere wazinthu kuti aziwombera. Kupanga makina oyendetsa ayenera kuyang'ana ntchito za extruder, ngati atulukira kuti akuyembekezeka kufinya extruder mpweya, ayenera yomweyo kudula gwero la magetsi ndi kukhala pambuyo makina kusiya kugwira ntchito pa mphuno extrusion kufa, kusintha mu mauna latsopano. (ma mauna akale popanda kuwonongeka pambuyo moto, akadali kupitiriza ntchito), anatsegulanso extrusion granulator, pulasitiki zipangizo kampani monga zinthu zatsopano, kwenikweni, zikhoza kusinthidwa kamodzi patsiku. Pambuyo extrusion, zinthu ayenera bwino mpweya zouma malinga ndi mmene zinthu zilili pamaso granulation.

Cholinga cha ndondomekoyi ndi kusintha zipangizo. Zindikirani: Kutentha kwa kutentha kwa zinthu zopangira kuyenera kusinthidwa malinga ndi zida zosiyanasiyana.

Extruder granulator ili ndi zowononga pawiri ndi zomangira imodzi, kudula kozizira ndi malo otentha, kampaniyo ikugwiritsa ntchito granulator yozizira.

3. Kupera ufa ndi njira yofunikira musanayambe kugubuduza kupanga chifukwa zinthu zomwe zimagwiritsidwa ntchito pogubuduza ndi ufa, ndipo zopangira zomwe zimagulidwa ndi msika ndi granule. Wogwiritsa ntchito granulator akayang'ana kuti mulibe zinthu zakunja pamakina, zida za granular zimayikidwa mu hopper, makina opera amayambika, ndipo liwiro la kudyetsa limasinthidwa kuti lipere. Pambuyo popera, zopangira ziyenera kuuma monga momwe ziyenera kukhalira, ndipo kutentha kwa kuyanika sikuyenera kupitirira 30 ℃.
Njirayi imayang'ana pamtundu wa ufa wopera, kukula kwa tinthu 30 ~ 60 mauna, tinthu tating'onoting'ono, palibe m'mphepete, ngodya, flake, tinthu tating'onoting'ono.
