Zomwe zimagwiritsidwa ntchito ndi thumba la simenti lopangidwa ndi ukonde woluka wopangidwa ndi pulasitiki, womwe pakati pake ndi silika woluka wopangidwa ndi mapulasitiki a polypropylene. Mwa izi, polypropylene imadziwika kuti ndi gawo lofunikira kwambiri popanga matumba apulasitiki a simenti ndipo imakhudza mtundu wa paketiyo. Tiyeni tipeze matumba a simenti ndi njira zopangira matumba apulasitiki a simenti.

Ulusi wa PP –> Chinsalu cha PP –> Filimu yansalu yokutidwa ndi PP –> Kusindikiza pamatumba a PP –> Zinthu zomalizidwa (kuwotcherera mpweya wotentha).
Chikwama chopangira simenti chimapangidwa movutikira kwambiri.

1.Pangani ulusi wa PP

Ma granules apulasitiki a PP amayikidwa mu hopper ya chipangizo chopangira ulusi, ndi makina oyamwa omwe amayikidwa mu extruder, ndikutenthedwa kuti asungunuke. The wononga extruders pulasitiki madzi ku nkhungu pakamwa ndi chosinthika kutalika ndi makulidwe monga pakufunika, ndi pulasitiki filimu aumbike mwa kupanga kuzirala madzi osamba. Kenako filimuyo imalowa mumtengo wodula kuti iphwanyidwe m'lifupi mwake (2-3 mm), ulusi umadutsa mu chotenthetsera kuti ukhazikike ndikuyika makina omangira.

Popanga ulusi, zinyalala za fiber ndi bavia za filimu ya pulasitiki zimabwezedwa ndi kuyamwa, kudula muzidutswa ting'onoting'ono, ndikubwezeretsanso ku extruder.

2.PP nsalu pepala

Mipukutu ya ulusi wa PP imayikidwa muzitsulo zozungulira za shuttle 06 kuti ziluke mu machubu a nsalu za PP, kupyolera mu makina omangira a nsalu ya PP.

3.Filimu ya PP yophimbidwa

Mpukutu wa nsalu wa PP umayikidwa ndi galimoto ya forklift pamakina opaka filimu, pepala la nsalu la PP limakutidwa ndi makulidwe a 30 PP pulasitiki kuti awonjezere mgwirizano wa nsalu zoteteza chinyezi. Mpukutu wa PP nsalu yokutidwa ndi kukulunga.

4.Kusindikiza pamatumba a PP

OPP film lamination ndiye chikwama chaukadaulo komanso chokongola kwambiri, ukadaulo wosindikizira pazithunzi za OPP, kenako ndikulumikiza filimuyi pampukutu wa nsalu za PP.

5.Anamaliza kudula mankhwala ndi kulongedza katundu

Matumba Osasindikizidwa kapena Flexo Woluka PP: Mipukutu ya PP yolukidwa imadutsa munjira yopinda m'chiuno (ngati ilipo), ndipo chomalizidwacho chimadulidwa. Kenako sokani kaye, sindikizani pambuyo pake, kapena soka pambuyo pake, sindikizani kaye. Zogulitsa zomalizidwa zimadutsa pama conveyor owerengera okha komanso kulongedza mabales.

Matumba opangidwa ndi PP okhala ndi filimu yosindikizira ya gravure m'mipukutu amadutsa munjira yodziwikiratu yopinda m'mbali, kukanikiza m'mphepete, kudula, kusoka pansi, ndi kulongedza.

Mwachidule, polypropylene polima ndiye chinthu chofunikira kwambiri popanga matumba apulasitiki a simenti ikafika popanga matumba onyamula simenti. Kusungirako, kuyendetsa, ndi kusamalira simenti ndizochitika zonse zomwe zimapindula ndi thupi, mankhwala, ndi makina a polypropylene.

Mapangidwe amatumba a simenti:

Matumba owongoka amalankhula makamaka: matumba apulasitiki opangidwa ndi polypropylene (PP m'Chingerezi) monga zopangira zazikulu, zomwe zimatulutsidwa ndikuzitambasulira kukhala ulusi wathyathyathya, kenako kuluka, kuluka, ndi kupanga thumba.

1. Matumba onyamula katundu wa mafakitale ndi zaulimi
2. Matumba onyamula zakudya
