Ko ngā rerekētanga o ngā ōwehenga monomer-ki-polymer i te wā o te tukanga whakaputa methyl methacrylate ka pā tika ki te whakahaere taumaha ngota, te māramatanga whatu, me te mahi miihini. Mā te urupare tukanga tonu ka taea te ine tika i ia taahiraa o te tukanga hanga methyl methacrylate, ka whakaitihia te utu nui o ngā hapa puranga. Mā ngā inenga ā-roto tonu i roto i te tūtohi rere o te tukanga methyl methacrylate ka kitea tonutia ngā kaiwhakahaere, ka tautoko i te polymerization radical pumau, inā koa i te wā o ngā nekehanga exotherm me te viscosity teitei.
E ai ki ngā whakamātautau ahumahi tata nei, mā te aroturuki tika ka whakaitihia te para o ngā rauemi mata mā te 10%–12%, ā, ka tautoko tika i te arotautanga o te hua. Mā ngā raraunga kiato ā-roto tūturu ka whakanui ake i te whai huatanga o ngā rauemi, ā, ka āwhina i te karo i ngā wā whakatā kore i whakamaheretia e pā ana ki ngā rerekētanga kāore i kitea, ngā rahunga polymerization rānei.
Te Hanga Pepa Kiriaku MMA

Kupu Whakataki
I roto i temetilakirirataI roto i te tukanga whakaputa, he mea nui te aroturuki tika i te parakore o te monomer me te tauhohenga mō te whakapūhuitanga ōrite. Ko ngā tikanga whakapūhuitanga papatipu i roto i te whakaputanga kiriaku me whakahaere pai te horopeta o te kaiwhakaoho rauropi me te tango wera.
Ko ngā tukanga whakapūhui pepa kiriaku e whakawhirinaki ana ki ngā pānui wā-tūturu mō te inenga, te whakaranu, me te whakarewa hei ārai i ngā hapa me ngā rauemi kāore i te tino tika. Mā te whakahaere tika i te mātotoru ka puta he māramatanga me te ōritetanga pai ake i roto i te hanga pepa kiriaku.
Tirohanga Whānui mō ngā Tukanga Ahumahi Matua
Ko te tukanga whakaputa methyl methacrylate e whakamahi ana i te methylation catalytic, te esterification oxidative tika rānei, hei hanga i te monomer MMA. Ko te methylation catalytic e whakamahi ana i ngā whakakōkī waikura Mg/Ga whakaranu, e whakatutuki ana i te whiriwhiringa me te hua teitei, me te whakaiti i te hanganga hua taha. Ko te methylation tika, i tauirahia ki Aspen Plus, ka taea te hangarua pai, ka taea te parakore o te MMA tae atu ki te 99.9% me te whakaiti i te whakamahinga pūngao.
Kei roto i te tūtohi rere o te tukanga methyl methacrylate ngā whakaurunga rauemi mata, ngā mahi purenga MMA, me ngā wāhanga whakapūmau. Kātahi ka tukuna te MMA kua whakapūmau ki ngā waeine polymerization papatipu mā roto i ngā paipa kati, hei whakaiti i te poke me te ngaronga.
Ko te tukanga whakapūhui matūriki methyl methacrylate e uru ana ki ngā kaiwhakaoho irahiko, te whakahaere wera tika, me te horapa tonu o te mekameka pūhui. Mā te whakahaere wera o te tauhohenga ka whakarite kia ōrite te huringa me te ārai i ngā tauhohenga werawera ohorere.
Ko te whakahaere i te tukanga hanga pepa kiriaku e whakawhirinaki ana ki te ine tika, te whakaranu kutikuti teitei, me te whakarewanga tauine. He mea nui ngā tikanga tukatuka pepa kiriaku pēnei i te whakamatao whakahaere me te whakahaere mirumiru mō te māramatanga me te ōritetanga. Me aroturukihia ia taahiraa kia mau ai te kounga hua.

Te Kīanga Wā-tūturu Ngā Wero Ine inAkiriuhiSheetMte hanga
Ko te ine i te mātotoru me te kukū ā-roto i roto i te tukanga hanga pepa kiriaku e pāngia tonutia ana e ngā wero mai i ngā mahi tukanga me te rerekētanga o ngā rauemi. Ko ngā pāmahana teitei i roto i ngā rohe werawera tauhohe ka whakatere i te poke o te pūoko, ka puta ai te nekeneke me te ngaronga o te whakatikatika. Ko te tukanga whakapūhui papatipu methyl methacrylate he tere te piki me te heke o te matotoru, ka whakararuraru i te pumau o te mita mātotoru, ā, me whakatikatika anō i ngā wā katoa.
Ka whakaiti tika te tika o te pūoko ā-roto i ngā matūriki kapia i whakatārewatia me te wehenga ā-wāhanga i te wā o te tukanga whakapūhui pepa kiriaku, nā te mea ka pāngia te urupare a te taputapu e te marara me te rere koretake. Tērā pea kei roto i ngā rohe i roto i te tukanga he ihirangi mirumiru rerekē, he hanganga microgel rānei, e whakapēkē ana i ngā raraunga kiato me te kukū nā te rerekētanga rangitahi.
Me kohikohi pono ngā mita ā-roto i ngā inenga tika, ā, me tu atu ki ngā huringa katoa o te tūtohi rere o te tukanga methyl methacrylate, tae atu ki te purenga MMA, te whakaū, me te tikanga polymerization papatipu i roto i te hanga kiriaku. E hiahiatia ana ngā rauemi me ngā hoahoa pūoko matatau hei whakawhāiti i te wā kore mahi me te whakarei ake i te tika o te ine puta noa i ia taahiraa o te hanga pepa kiriaku.
Ngā Painga o te Matotoru ā-Rārangi LonnmeterNgā Mita
Te mātotoru ā-roto o te mita roa me temita kukūKa tukuna ngā inenga tika, kore-whakaeke puta noa i ia wāhanga o te tukanga hanga pepa kiriaku, tae atu ki te tukanga whakapūhui papatipu methyl methacrylate. Mā ngā wā urupare pūoko i raro i te 0.5 hēkona ka taea te whakahaere tika i te tukanga, e tautoko ana i te inenga me te maka tika i te wā o te tukanga whakapūhui pepa kiriaku.
Ka ātete te hoahoa pakari o te taputapu i te nekenekehanga o te pūoko i puta mai i ngā pāmahana teitei, ngā matūriki kapia i whakatārewatia, te ihirangi mirumiru rerekē, me te hanganga microgel. Ka mau tonu ngā taputapu mita roa ki te ±0.003te tika o te g/cm³ mā roto i ngā rohe pāmahana e neke haere ana me ngā āhua rerekē.
Whakaitihia ngā puranga me ngā para rauemi kāore i te tino tika. Tauwhāitihia ngā taputapu hei whakauru tika ki te tūtohi rere o te tukanga methyl methacrylate me te tikanga polymerization papatipu i roto i te hanga kiriaku. Whakapā atu ki te miihini hokohoko Lonnmeter inaianei tonu.
