Qaabka utility wuxuu khuseeyaa bacda sibidhka isku dhafan ee ka samaysan shabag tolan oo ka samaysan caag, kaas oo lakabka dhexe uu yahay xariir tolsan oo ka samaysan balaastikada polypropylene. Kuwaas waxaa ka mid ah, polypropylene ayaa loo arkaa inay tahay qaybta ugu muhiimsan ee habka wax soo saarka bacaha sibidhka waxayna saamaysaa tayada baakadaha. Aynu ogaano alaabta bacaha sibidhka iyo habka wax soo saarka bacaha sibidhka ee dhamaystiran

PP yarn -> xaashida dharka PP-dahaarka leh -> Filimka dharka PP ee daboolan -> Ku daabacida bacaha PP -> Alaabooyinka la dhammeeyey (alxanka hawada kulul).
Khadka wax-soo-saarka bacda sibidhka waxaa lagu soo saaraa hab aad u adag.

1.Samee dunta PP

PP-ga balaastigga ah waxaa lagu shubaa hopper ee qalabka samaynta dunta, by mishiinka nuugista la geliyo extruder, iyo kuleyl si ay u dhalaaliso. furku wuxuu balaastigga dareeraha ah u saaraa afka caaryada leh dhererka iyo dhumucdiisuna waa la hagaajin karaa sida loo baahdo, iyo filim caag ah ayaa la sameeyay iyada oo loo marayo samaynta qubeyska biyaha qaboojinta. Dabadeed filimku wuxuu galaa shafka gooya si uu u jeexo ballaca loo baahan yahay (2-3 mm), duntu waxay dhex martaa kuleyliyaha si loo dejiyo ka dibna la dhigo mashiinka dabaysha.

Inta lagu jiro habka abuurista dunta, qashinka fiber-ka iyo bavia ee filimka caagga ah ayaa lagu soo celiyaa nuugista, googooyaa qaybo yaryar, oo dib ugu soo celisa soo saarista.

2.Xaashiyaha dharka PP ee tolan

Duubabka dunta PP waxa la geliyaa 06 xidhidhiyaha wareegta ah si loogu tolo tubooyinka dharka PP, iyada oo loo marayo habka dabaysha PP.

3.Filimka dharka PP ee daboolan

Duubabka PP-ga waxaa lagu rakibay gawaarida fargeetada ah ee mashiinka dahaarka filimka, xaashida dharka PP waxaa lagu dahaadhay dhumucdiisuna tahay 30 PP caag ah si loo kordhiyo curaarta dharka aan qoyaanka lahayn. Duubista maro PP oo dahaaran oo duuban.

4.Ku daabacida bacaha PP

Daabacaadda filimka OPP waa bacda ugu xirfadda iyo quruxda badan, tignoolajiyada daabacaadda gravure ee filimka OPP, ka dibna ku tallaalida filimkan duub duuban oo PP ah.

5.Goynta iyo baakaynta alaabta oo dhammaatay

Aan Daabicin ama Flexo Daabacan Bacaha Tolmada leh ee PP: Duubabka duuban ee PP-ga waxaa la dhex maraa habka laalaabida miskaha (haddii ay jiraan), alaabta dhammaatayna waa la gooyaa. Dabadeed marka hore tolo, dabo mar dambe, ama hadhow, soo daabac marka hore. Alaabooyinka la dhammeeyay waxay maraan tirinta tirinta tooska ah iyo baakadaha baalasha.

Bacaha tolan ee PP ee leh filimka daabacaadda gravure ee duubka ku jira waxaa loo dhex maraa hab toos ah oo dhinaca laalaabista, cidhifyada geesaha, jarista, tolida hoose, iyo xirxirida.

Marka la soo koobo, polypropylene polymer waa walxaha la doortay inta lagu jiro habka wax soo saarka bacaha sibidhka marka ay timaado soo saarista bacaha sibidhka. Kaydinta, gaadiidka, iyo maaraynta sibidhka waa dhammaan waxqabadyada ka faa'iidaysta jirka, kiimikaadka, iyo qalabka farsamada ee polypropylene.

Tilmaamaha bacaha sibidhka:

Bacaha tolsan ayaa inta badan hadlaya: bacaha tolmada leh waxay ka samaysan yihiin polypropylene (PP Ingiriisi) oo ah alaabta ceeriin ee ugu weyn, taas oo la sii daayo oo la fidinayo dun fidsan, ka dibna timo, timo, iyo bac.

2. Bacaha baakadaha cuntada
