Site na mmepe nke teknụzụ ọhụrụ, mmepụta nke nylon 6 abanyela n'ọkwa nke teknụzụ dị elu dị elu.Dị ka ojiji dị iche iche si dị, usoro polymerization nke nylon 6 nwere ike kewaa n'ime ndị a.
1. Usoro polymerization nke abụọ
Usoro a bụ ụzọ abụọ polymerization, ya bụ pre-polymerization na post-polymerization ụzọ, nke a na-ejikarị eme ihe na-emepụta ụdọ ụlọ ọrụ na nnukwu viscosity.A na-ekewa ụzọ abụọ nke polymerization na pre-polymerization pressurization na post-polymerization decompression.N'ime usoro mmepụta ihe, a na-eme nrụgide nrụgide ma ọ bụ nkwụsịtụ dịka ntụnyere oge polymerization, onye ọ bụla na ngwaahịa na obere-poly olu.N'ozuzu, usoro nkwụsị nke post-polymerization dị mma, ma ọ na-achọkwu ego, na ọnụ ahịa dị elu, na-esote nrụgide dị elu na nrụgide nkịtị n'ihe gbasara ọnụ ahịa.Otú ọ dị, ụgwọ ọrụ nke usoro a dị ala.Na pre-polymerization pressurization na post-polymerization decompression ụzọ mmepụta, n'oge pressurization ogbo, a na-agwakọta ihe nke mmepụta na mgbe ahụ niile na-etinye n'ime reactor, na mgbe ahụ, a na-eme ka mgbanaka mgbanaka mmiri na-emeghe na mmeghachi omume polymerization akụkụ. na okpomọkụ a kapịrị ọnụ.Usoro a bụ mmeghachi omume endothermic.Okpomọkụ dị n'akụkụ elu nke tube polymer.N'oge usoro nrụgide, polymer na-anọ na tube polymer ruo oge ụfọdụ wee banye na polymerizer, ebe viscosity nke polymer na-emepụta ga-eru ihe dị ka 1.7.
2. Usoro polymerization na-aga n'ihu na nrụgide nkịtị
Usoro a na-eji maka mmepụta nke anụ ụlọ rịbọn nke naịlọn 6. Atụmatụ: Nnukwu na-aga n'ihu polymerization na-nakweere na okpomọkụ nke ruo 260 ℃ na a polymerization oge maka 20 awa.A na-enweta oligomer fọdụrụ na mpaghara ahụ mgbe mmiri ọkụ na-aga megide ugbu a.A na-anabatakwa njikwa nkesa nkesa DCS na ihicha ikuku amonia.Usoro nke mgbake monomer na-anabata teknụzụ nke na-aga n'ihu na-ekpo ọkụ na-enwe mmetụta atọ na ntinye uche na nkwụsịtụ nkwụsị na ntinye nke mmiri a na-amịpụta.Uru nke usoro: Ọmarịcha arụmọrụ na-aga n'ihu nke mmepụta ihe, mmepụta dị elu, àgwà ngwaahịa dị elu, obere mpaghara na-arụ ọrụ na mmepụta ihe.Usoro a bụ nkà na ụzụ na-ahụkarị na mmepụta nke rịbọn ụlọ dị ugbu a.
3. Ụdị nkwụsịtụ ụdị autoclave polymerization usoro
A na-eji ya eme ihe n'ọtụtụ ebe n'ichepụta obere plastik injinia.Ọnụ ọgụgụ mmepụta bụ 10 ruo 12t / d;Nsonaazụ nke otu autoclave bụ 2t/batch.N'ozuzu, nrụgide na usoro mmepụta bụ 0.7 ruo 0.8mpa, na viscosity nwere ike iru 4.0, na 3.8 na oge nkịtị.Nke ahụ bụ n'ihi na ọ bụrụ na viscosity dị oke elu, mmepụta ga-adị ntakịrị.Enwere ike iji ya mepụta pa 6 ma ọ bụ pa 66. Usoro ahụ nwere usoro mmepụta ihe dị mfe, nke dị mfe ịgbanwe ụdị dị iche iche na mgbanwe maka mmepụta.
