Infrared Rotary Dryer + Sisitemu ya SSP
Polimerisiyasi ikomeye (SSP) nubuhanga bwingenzi bwo kugera "kuzamura ubuziranenge" na "icyatsi kibisi" murwego rwa PET.
LIANDA MACHINERY irahuza cyaneINFARARED ROTARY DRYER hamwe na sisitemu ya SSPgukora igisubizo gihuriweho na "Gukuraho neza neza - Kwiyongera neza kwijimye - Igikorwa cyo gukoresha make". Ibi bitezimbere cyane imitungo ya rPET, ituze ryumuriro nubuziranenge bwimiti. Iri koranabuhanga rifite uruhare rudasubirwaho mu nganda za PET (cyane cyane izitunganyirizwa mu rwego rwo hejuru kandi zitanga umusaruro ushimishije).
Niba ukeneye kumenya ibipimo byihariye cyangwa iboneza ryibikoresho, nyamuneka hamagara Lianda Machinery kugirango ubone ibisubizo bya tekiniki byabigenewe
Icyiciro kibanziriza gutunganya
Kuma: PET ni hygroscopique kandi igomba gukurwaho na IRD (Nyuma ya IRD, ubuhehere bwa nyuma bwa PET pp 50 ppm) kugirango wirinde hydrolysis no kwangirika kubushyuhe bwinshi.
Crystallisation: PET pelletes ikozwe na IRD (impamyabumenyi ya kristalisiti igera kuri 30-40%) kugirango ibuze PET pellet gukomera cyangwa gushonga mubushyuhe bukabije bwakurikiyeho, mugihe bitanga ibidukikije bihamye kugirango polycondensation itangire.
Icyiciro gikomeye cya Polycondensation Icyiciro
Conditions Ibisabwa:
Ubushyuhe: bugenzurwa kuri 200-2240 ℃ (munsi ya PET gushonga 250-2260 ℃, komeza ushikamye).
Vacuum / inert itembera: azote irashyirwaho kandi vacuum ikururwa kugirango ikureho reaction byproduct Ethylene glycol (EG) kandi iteze imbere polycondensation mubyerekezo byiza.
Reaction reaction yimiti:
Hydroxyl (-OH) na carboxyl (-COOH) kumpera yumunyururu wa PET ihura na reaction ya konte kugirango ikore ester bond (-COO-), mugihe irekura Ethylene glycol (EG), kuburyo urunigi rwa molekile rukomeza kwaguka kandi uburemere bwa molekile (viscosity IV).
Imashini ya Lianda ihuza ibyuma byumye (IRD) hamwe na sisitemu ya SSP, byihuta kandi bingana gushyushya ibikoresho binyuze mumirasire ya infragre, bigabanya igihe cyo kwitegura, kandi bigahindura uburyo bwo kohereza imbaga mu buryo bukomeye, kuburyo sisitemu yose ifite ibiranga imikorere ihanitse kandi ikabika ingufu, ubushobozi bunini bwo gutunganya, hamwe n’ibicuruzwa bihanitse cyane, bikwiranye cyane cyane n’umusaruro mwinshi wa PET.
LIANDA MACHINERY ihuza Infrared kristal yumye (IRD) hamwe na sisitemu ya SSP, ikoresha umurongo wa infragre kugirango ushushe vuba kandi uringaniye ibikoresho, bigabanya igihe cyo kubanza kuvura, kandi uhindure uburyo bwo kohereza ibintu muburyo bukomeye, bituma sisitemu yose ikoresha ingufu nyinshi, hamwe nubushobozi bunini bwo gutunganya hamwe nibicuruzwa bihamye. Birakwiriye cyane cyane kubikorwa binini byo mu rwego rwo hejuru byongera umusaruro wa PET.
Niba ukeneye ibisobanuro birambuye bya tekiniki cyangwa ibisubizo byabigenewe, urashobora kuvugana na Lianda Machine kugirango ubone ubufasha bwumwuga
Hamwe na tekinoroji yumye ya infragre, iratahura guhuza "kwanduza + gukama + kongera imbaraga", bigateza imbere PET ikoreshwa neza.
| Ibyiza | Imikorere yihariye |
| Ibiro bya molekile byiyongera | Ubwiza bwimbere (IV) bwiyongereye cyane kandi imbaraga za mashini (imbaraga za tensile, moderi ya elastique) zitezimbere 30-50%. |
| Gutezimbere ubushyuhe | Ingingo yo gushonga (Tm) yiyongereyeho gato (hafi 5-10 ℃), kristu iratera imbere, kandi ubushyuhe bwo hejuru bwongerewe imbaraga (bukwiranye nicupa ridashobora kwihanganira ubushyuhe). |
| Kunoza ubuziranenge bwimiti | Kuraho monomer zisigaye (nka formaldehyde, acetaldehyde) na oligomers (ibirimo bigabanuka kugeza munsi ya 50 ppm), byujuje ubuziranenge bwibiribwa. |
| Ibikoresho byitondewe | Imyitwarire ikomeye irinda kwangirika kwubushyuhe bwatewe nubushyuhe bwo hejuru kandi birakwiriye cyane cyane kugarura ubuziranenge bwa PET. |
| Guhindura inzira | Ubukonje bwibicuruzwa byanyuma birashobora kugenzurwa neza muguhindura ubushyuhe, igihe na dogere ya vacuum, bityo bikuzuza ibisabwa bitandukanye. |
Gusaba
PET
Production Icupa ryinshi rifite icupa:
Gutezimbere uburinganire bwa PET, bigabanya gucika intege kumubiri wicupa, bikwiranye nibinyobwa bya karubone, ibikoresho byo kwisiga, nibindi.
Development Guteza imbere amacupa adashyuha:
Binyuze kuri SSP, agaciro ka IV kongerewe hejuru ya 0,85 dL / g, kibereye amacupa y'ibinyobwa yuzuye ubushyuhe (nko gupakira icyayi ako kanya, ikawa).
Kongera kuzamura PET kuzamura ubuziranenge
Gutunganya ibicupa byongeye gukoreshwa:
Nyuma y’umuguzi PET icupa rivurwa hamwe nuburyo bukomatanyije bwo "gukama - kwanduza - kongera imbaraga" kugira ngo ukureho EG ， Acetaldehyde, VOC no kugarura ububobere, kubisubiza mu byiciro by’ibiribwa cyangwa mu rwego rw’inganda (nka fibre, impapuro).
Value Agaciro k'ubukungu kazenguruka:
Hamwe na tekinoroji yumye (IRD), "ingufu nkeya zidafite imbaraga + zongera ingufu za viscosity" bigerwaho mugutezimbere-gufunga gutunganya PET
Umwanya wo gukora plastike
Preparaction Gutegura neza PET:
Umusaruro wa PET (IV> 1.0 dL / g) kugirango ukoreshwe mu bice by'imodoka (nk'ibikoresho, ibyuma), amazu ya elegitoroniki n'amashanyarazi, n'ibindi, kugirango usimbuze plastiki yubuhanga gakondo.
