Polypropylene (PP) e lohiloeng mokotla Coating Technology

1. Kakaretso ea Kopo le Boitokisetso:
Thepa e khethehileng ea ho roala ha polypropylene e sebelisoa haholo-holo bakeng sa ho roala mokotla o entsoeng ka polypropylene le lesela le lohiloeng. Ka mor'a ho roala, mekotla e lohiloeng e entsoeng ka ho roala e ka sebelisoa ka ho toba ntle le mekotla ea polyene. matla le ts'ebetso e akaretsang ea mokotla o lohiloeng li ntlafatsoa hobane filimi ea potoloho ea polypropylene e koahetsoe ka ho toba mokotleng o lohiloeng, 'me tšebeliso e bonolo,' me litšenyehelo tsa ho etsa thepa le tsona li fokotsehile.

State Building Materials Agency (National Building Materials Bureau) e thehile mantsoe & lt;1997>No.079 ka November 1997, e hlalosang hore mekotla e lohiloeng e lohiloeng e tlameha ho sebelisoa bakeng sa ho paka samente le lihlahisoa tse ling. Ka nako e ts'oanang, ka nts'etsopele ea indasteri ea liphutheloana tsa malapeng, mefuta e mengata ea tšebeliso le litekanyetso tsa pente PP li ile tsa eketseha butle-butle. Moetsi oa pele oa polasetiki o rekile mohala oa tlhahiso ea polasetiki le mekotla e lohiloeng e kopantsoeng, e fetotsoeng ho tloha mokotleng oa pele oa PE oa ka hare oa PP ho ea ho mokotla oa sekoaelo o nang le likarolo tse peli ho e le 'ngoe le mokotla o kopantsoeng oa pampiri oa pampiri tse tharo ho e le' ngoe, le tlhoko ea 'maraka ea sehlopha. PP e ntse e eketseha letsatsi le letsatsi. Phepelo ea PP ea pente ea lapeng e tiile.
ho fanoe ka lintlha tse ka holimo, re itšetlehile ka kakaretso T30S le 2401 (MFR = 2 ~ 4 g / 10min) 'me ka katleho re ntlafalitse lisebelisoa tse khethehileng tsa sehlopha sa ho roala (MFR = 20 ~ 32 min, matla a tensile 24.0 MPa) ka ho senyeha ho laoloang ka mor'a ho kopanya.

Nakong ea ts'ebetso ea nts'etsopele, ho ile ha etsoa liteko tse 'maloa mabapi le khetho ea li-regulator tsa boima ba limolek'hule le lisebelisoa tse ling, ho kopanya le ho etsa polasetiki ea lisebelisoa tse tala le mekhoa e amanang le eona. Ka mor'a ho hlahlojoa hantle, mokhoa oa ho qapa le ho hlahisa liphahlo tsa PP li ile tsa khethoa. theha mohala oa tlhahiso ea bongata. liphello tse khotsofatsang li 'nile tsa fumanoa ka likopo tse ngata, tse lulang li bonahatsa boleng bo tsitsitseng ba sehlahisoa, metsi a qhibilihisang hantle, sebopeho sa filimi e ts'oanang, ho fokotseha ho fokolang, matla a phahameng a peel le ho khomarela holimo. 2. melemo ea moruo e reriloeng:

Theko ea thepa e khethehileng ka tone e le 'ngoe ea ho roala e ka ba li-yuan tse 2,000 ho feta theko ea thepa e tala. Kamora ho theola lisebelisoa, basebetsi, lits'ebeletso, ho theoha ha theko ea mochini le litšenyehelo tse ling tsa li-yuan tse 150, phaello e felletseng ka thane e le 'ngoe ea thepa e khethehileng ke li-yuan tse 1500. Palo ea selemo le selemo ea mohala oa tlhahiso (e baloang ke extruder e nang le screw bophara ba 65) ke lithane tse 350-450, 'me lekhetho la selemo le selemo la letlooa le ka fihla ho feta 500000 yuan. haeba u sebelisa screw extruder e kholo, tlhahiso e phahame. Hajoale, China e na le lifeme tse kholo tse lohiloeng tsa mekotla tse fetang 1000, metse le litoropo le likhoebo tse ikemetseng tse ngata. Morero o na le litebello tse pharaletseng.
Ea bobeli, theknoloji ea ho lokisetsa ea "polypropylene cooling masterbatch" ke "polypropylene-based masterbatch", haholo-holo e sebelisetsoang ho fokotsa mocheso oa polypropylene le lihlahisoa tsa polasetiki ha li sebetsa, haholo-holo ka polypropylene spinning e ntle haholo, empa hape e sebelisoa ho hlahisa polypropylene. filimi, mekotla ea masela, monofilament, lihlahisoa tsa ho bopa ente le tsona li fumane litholoana tse ntle.
index ea ts'ebetso ea mantlha: eketsa 1 ~ 5% pholileng masterbatch ho resin ea polypropylene bakeng sa ts'ebetso; e ka finyella lintlha tse latelang: limaraka tsohle tsa polypropylene resin li ka hlahisa boleng bo phahameng ba C round fine denier fiber. Mocheso oa ho ohla le oa polasetiki o ka fokotsoa ho tloha ho 20°C ho ea ho 50°CC; ntlafatsa boleng ba fiber polypropylene le lihlahisoa tsa polasetiki; ntlafatsa katleho ea tlhahiso; le ho fokotsa tshilafalo ya tikoloho.

Sebaka sa ts'ebeliso: polypropylene spinning, polypropylene film blowing, polypropylene loven bags, monofilament
