3. Plasticizers ne Nnuru Titiriw: Nneɛma a Wɔde Yɛ Nneɛma a Ɛma Nkɔanim
Phthalate Nneɛma a Wɔde Yɛ Plastic:
PA ne ade a edi kan a wɔde yɛ diisononyl phthalate (DINP) ne diethyl phthalate (DEP), a wɔde di dwuma kɛse wɔ PVC nneɛma te sɛ agode, ntama a wɔde hyɛ, ne nnuruyɛ mfiri mu. Saa plasticizers yi ma wotumi yɛ nsakrae bere a ɛkɔ so di EU REACH mmara a ɛfa awuduru a ɛba fam ho (sɛ nhwɛso no, wɔ mmofra nneɛma mu) so.
Nnuru a Wɔde Yɛ Ntam:
Wɔ nnuruyɛ mu no, wɔde PA a efi mu ba no di dwuma wɔ nnuru te sɛ nnuru a ɛko tia ɔyare mmoawa ne nnuru a ekum fungal. Sɛ nhwɛso no, edi dwuma wɔ cephalosporin nnuru a ekum ɔyare mmoawa a wɔyɛ mu, a ɛho hia kɛse wɔ ɔyare mmoawa a wɔde sa ɔyare mmoawa mu wɔ wiase nyinaa no mu.
4. Kuadwuma ne Nwansena a Wɔko Tia: Ano aduru a Ɛkɔ So Daa
Nnuru a Ekum nkoekoemmoa ne Nnuru a Ekum Nwansena:
Wɔde nnuru a egyina PA so na ɛyɛ nneɛma a wɔde bɔ nnɔbae ho ban, te sɛ pyrethroids a wɔayɛ de siw nkoekoemmoa ano. Wɔ Amerika Kesee Fam soyabean mfuw mu no, saa nneɛma yi boa ma wɔbɔ nnɔbae ho ban fi mmoawa a wɔsɛe nnɔbae ho bere a ɛmma nneɛma a atwa yɛn ho ahyia no nsɛe pii no.
Polymers a Ɛtumi sɛe Nkwammoaa:
Sɛ́ monomer wɔ plastic a ɛtumi sɛe no mu no, PA boa ma wɔyɛ nneɛma a wɔde kyekyere nneɛma a ɛnyɛ nea ɛde abɔdeɛ ba (sɛ nhwɛsoɔ no, nnuan a wɔde gu afifideɛ mu) a ɛtew ahotosoɔ a wɔde to nneɛma a wɔde petroleum ayɛ so.
5. Laboratory ne Nhwehwɛmu a Wɔde Di Dwuma
Nkwammoaa a Wɔde Yɛ Nneɛma:
PA yɛ reagent a ɛyɛ adwuma pii wɔ adesua ne mfiridwuma mu nhwehwɛmubea ahorow ma reactions te sɛ Friedel-Crafts acylation, a wɔde yɛ ketones a ɛyɛ huam ne dyes. Ɛsan nso ma ɛyɛ mmerɛw sɛ wɔbɛyɛ phthalimide, ade titiriw a ɛwɔ ntam wɔ nnuruyɛ ne kuayɛ mu nnuruyɛ mu nhwehwɛmu mu.
Polymer Nyansahu:
Wɔde di dwuma wɔ polymer labs de sua abusuabɔ a ɛda polyesters ntam ne ne su ntam, na ɛma wotumi yɛ nneɛma a ɛkɔ anim a wɔde yɛ ahunmu ne ɛlɛtrɔnik mfiri (sɛ nhwɛso no, nneɛma a wɔde kata satellite so a ɛko tia ɔhyew).
