ʻO ka ʻike maʻamau o ka plastic masterbatch
Pākīpika masterbatchHiki ke ʻike ʻia he polymersmasterbatch.Hiki ke hana ʻia nā polymers mai nā ʻano 'mers' like ʻole e kū nei no nā ʻāpana kemika.Hoʻokumu ʻia ka hapa nui o nā kemika mai ka aila a i ʻole nā hydrocarbons ʻē aʻe.E like me ka mea i ʻike ʻia, hana ʻia ka hydrogen a me ke kalapona.No laila, hana ʻia nā plastics me ka hydrogen a me ke kalapona i hui pū ʻia e hana i mers (e like me ka ethylene a propylene) a laila pili kēia mau mers e hana i nā kaulahao a i ka lōʻihi o kēia mau kaulahao e lilo i 'poly' maʻamau i ka wā liʻiliʻi. Ua hui pū ʻia nā 100 o nā mers, loaʻa iā mākou kahi mea plastic/polymeric.
Pākīpika masterbatchʻO ka ʻohana thermoplastic i hana ʻia me nā molekole kaulahao lōʻihi me ka nui o ke kalapona a me ka hydrogen i kapa ʻia he polymers.Hoʻohui ka huaʻōlelo i ka "poly" e pili ana i ka nui a me ka "mer" e pili ana i nā ʻāpana molekala hou i hoʻopaʻa ʻia.ʻO nā ʻāpana mer o nā ʻano plastik like ʻole, ka ikaika o nā paʻa molekala e paʻa ana i nā mers i kekahi i kekahi a me ka lōʻihi o nā kaulahao polymer nā mea hoʻoholo mua o nā waiwai plastic.ʻOi aku ka nui o nā ʻano ʻāpana mer hoʻokahi.
PākīpikamasterbatchʻO ka ʻohana thermoset ʻoiai e like me nā mea i hōʻike ʻia ma luna nei he mau pilina like ʻole ma waena o nā mers me nā loulou keʻa e hāʻawi iā lākou i nā waiwai like ʻole me nā hihia e hiki mai ana ka hiki ke hoʻoheheʻe ʻia ma mua o ka pohō ʻana i ka piʻi ʻana o ka mahana.
E wāwahi ana i ka masterbatch plastic
Nui ʻinoplastic masterbatchua naha i ka pahūpahū!
Pahū mahu ma ka nui.Akā ʻaʻole wale.
Aia kekahi pūʻulu o nā thermoplastics i loaʻa mai kahi mea maka i kapa ʻia ethylene.A hana ʻia ka ethylene ma nā ʻano ʻano like ʻole, ka hapa nui mai ka aila a i ʻole ke kinoea meaʻai.
ʻO kahi ala kaulana loa, ʻo ia ka hoʻokomo ʻana i ka meaʻai i loko o ka pahu pahu a me nā hopena ethylene, a me nā mea ʻē aʻe kekahi.Hoʻopili ʻia ka ethylene i polyethylene a i ʻole polypropylene ka nui akā ʻaʻole wale.Hana ʻia ʻo PVC, PS, PET, butadiene.
Eia kahi ʻāpana mai kahi ʻatikala e wehewehe ana i kēlāplastic masterbatchʻoi aku ka maikaʻi:
“ʻO ka Ethylene ka wahi hoʻomaka no nā huahana hope ʻehā: polyethylene (ʻekolu ʻano: LDPE, LLDPE, a me HDPE), ethylene oxide, ethylene dichloride (ka mea mua i ka vinyl chloride monomer), a me ka ethylbenzene (ke kumu o ka styrene).ʻO nā huahana liʻiliʻi liʻiliʻi, ʻoi aku ka nui o nā huahana ʻoi aku ka linear α-olefins, vinyl acetate monomer, a me ka ethanol synthetic, etc.
Eia ka papa inoa o kekahi ethylene kaulanamasterbatchhuahana:
| PVA Poly(vinyl acetate), poly(vinyl alcohol) | PET Poly(ethylene terephthalate) |
| PVC Poly(vinyl chloride) | PS Polystyrene |
| LLDPE Linear polyethylene haʻahaʻa haʻahaʻa | PEG Poly(ethylene glycol) |
| LDPE polyethylene haʻahaʻa haʻahaʻa | HDPE Polyethylene kiʻekiʻe kiʻekiʻe |
ʻO ke ala nui o ka hana ʻana i ka ethylene, ʻo ia nā meaʻai kinoea hoʻoheheʻe mahu (ethane, propane, a butane) a i ʻole nā meaʻai wai (naphtha a i ʻole ka aila kinoea).Ma kahi wela kiʻekiʻe loa mai 850 Celsius degere a ʻoi aku paha ke kiʻekiʻe, ua holo ʻia kēlā mau ʻōnaehana systematic o ka mechanized non-catalytic cracking.ʻO Ethylene ka huahana i manaʻo ʻia;akā, ua hana pū ʻia nā molekole kūkulu hale waiwai ʻē aʻe, e like me propylene, butadiene, a me benzene.
ʻO ka hua o kēlā me kēia coproduct ka hapa nui o ka mea hānai i hoʻohana ʻia.ʻAʻole hāʻawi ʻia nā coproducts i ka haki ʻana i ka ethane;akā, hāʻawi ka naphtha i ka nui o ka propylene, butadiene, a me benzene.E like me ka nānā ʻana ma ka honua holoʻokoʻa, hiki ke ʻike ʻia ka māhā ʻana ma ke ʻano he kumu waiwai nui o ka butadiene, propylene a me nā kumu waiwai nui o benzene.Hōʻike ʻia ke kiʻi ma lalo nei i ke ʻano o ka moʻo ʻōnaehana o ka pohā ʻana i ka mahu mechanized ma ke ala maʻalahi loa.
