Elastomer ea polyurethane ke mofuta oa thepa e sebelisoang haholo, e na le ho tenyetseha ho hoholo, ho tšoarella le ho hanyetsa ho tsofala, kahoo e sebelisoa haholo maemong 'ohle a bophelo. E 'ngoe ea lintlha tsa bohlokoa tlhahisong ea li-elastomer tsa polyurethane ke tšebeliso ea li-catalyst tse potlakisang liketso tsa lik'hemik'hale nakong ea ho thehoa ha thepa ea ho qetela. Li-catalyst tsena li bohlokoa bakeng sa ho laola ts'ebetso ea polymerization, ho netefatsa hore thepa e lakatsehang ea elastomer ea finyelloa. Har'a li-catalyst tse fapaneng tse fumanehang, MXC-A33 e na le motsoako o ikhethang o ka sebelisoang mefuteng e mengata ea li-foam tsa polyurethane le li-elastomer.
Ke engMXC-A33?
MXC-A33 ke sehokelo sa polyurethane se ntlafatsang karabelo pakeng tsa polyols le isocyanate, e leng dikarolo tse ka sehloohong tsa thepa ya polyurethane. Sehokelo sena se entswe ka 33% TEDA (triethylene diamine) le 67% DPG (monoconjugated dipropylene glycol). Sebopeho sena se ikgethang se fana ka tshebetso e ntle haholo tlhahisong ya foams tsa polyurethane le elastomers.
- TEDA (Triethylenediamine): Sesebediswa se sebetsang hantle sa amine e phahameng se kgothaletsang karabelo ya gelling pakeng tsa dihlopha tsa hydroxyl le isocyanate.
- DPG (Monoconjugated Dipropylene Glycol): Sethapo se thusang ho fokotsa ho teteana le ho ntlafatsa ho kopanya ha thepa, ho netefatsa ts'ebetso e boreleli ea karabelo.
Tšebeliso ho Polyurethane Elastomers
MXC-A33 e sebelisoa haholo tlhahisong ea li-elastomer tsa polyurethane ka lebaka la phello ea eona e leka-lekaneng ea catalytic, e netefatsang hore karabelo ea polymerization e etsahala ka lebelo le laoloang. Phetoho ena e laoloang e bohlokoa bakeng sa tlhahiso ea li-elastomer tse nang le thepa e lakatsehang ea mechini joalo ka ho tenyetseha, matla a ho tsitlella le ho hanyetsa ho tsofala.
Sesebediswa sena se kgothaletsa ho thehwa ha dibopeho tse tshwanang tsa polymer tse hokahaneng, tse ka fihlelang tshebetso ya di-elastomer ditshebedisong tse hlokang boiteko. Di-elastomer tsa polyurethane tse entsweng ka MXC-A33 di sebediswa haholo dikarolong tsa dikoloi, di-roller tsa diindasteri, le ditiiso tse sebetsang hantle, tse behang ditlhoko tse phahameng ho tshwarelleng ha tsona le ho tenyetseha ha tsona.
Qetello
Tšebeliso eali-catalyst tsa polyurethanejoalo ka MXC-A33 tlhahisong ea elastomer ke ntlha ea bohlokoa ho netefatseng ts'ebetso le ts'epo ea thepa. Motsoako oa eona o ikhethang oa TEDA le DPG o etsa hore e sebetse hantle haholo bakeng sa lits'ebetso tsa foam le elastomer, e nolofalletsang bahlahisi ho hlahisa lihlahisoa tsa boleng bo holimo le tse tšoarellang bakeng sa liindasteri tse fapaneng.
