AKWỤKWỌ AWU
Ajị anụ nwere ụdị ọdịdị pụrụ iche na ọrụ mkpuchi dị mma, ndị na-azụ ahịa na-anabatakwa ya nke ukwuu maka mmetụta aka ya dị nro, agba na-egbuke egbuke, dị arọ na uwe dị mma. Site na mmụba na-aga n'ihu nke ụkpụrụ ndụ mmadụ, ihe ndị a chọrọ maka imecha akwa ajị anụ na-abawanye.
Mechanism nke onye na-emecha ajị anụ
Ihe ndị na-emecha ajị anụ na-abụkarị amino silicone ma ọ bụ ihe mgbochi silicone. N'ihi mmekọrịta dị n'etiti amino otu na carboxyl dị iche iche n'elu ajị anụ, ọ nwere ike ịbawanye mmekọrịta nke silicone na eriri, meziwanye nguzogide ịsacha. N'otu oge ahụ, mmekọrịta dị n'etiti amino Groups na carboxyl otu na-enye siloxane aka ịrapara n'elu fibers n'ụzọ ntụgharị, na-emepụta mmetụta aka dị mma ma na-ebelata ọnụ ọgụgụ esemokwu n'etiti eriri, si otú a na-enweta ezigbo nro na njedebe dị nro.
Dị ka e gosiri na ọnụ ọgụgụ a, ụdị dị iche iche nke ike nwere ike ịmepụta n'etiti nnukwu ụmụ irighiri ihe nke na-emecha ihe na-emecha na ajị anụ, yana n'etiti nnukwu ụmụ irighiri ihe na-emecha, si otú ahụ na-emepụta usoro njikọ n'etiti eriri, na ịba ụba. elasticity na wrinkle mgbake akụkụ nke ákwà.
Eserese atụmatụ nke ike mmekọrịta dị n'etiti molekul macro nke onye na-emecha ihe na eriri
Mara:
A bụ covalent njikọ kpụrụ n'etiti finishing gị n'ụlọnga macro molecule na eriri nnukwu molekul;
B bụ njikọ ion;
C bụ njikọ hydrogen;
D bụ van der Waals ike; E bụ njikọ covalent kpụrụ n'etiti nnukwu ụmụ irighiri ihe na-emecha.
Ihe kpatara mmụba dị ịrịba ama na ike akwa akwa akwa bụ na onye na-emecha ihe nwere ike ịbanye n'ime eriri ndị ahụ, na-emepụta ihe nkiri si n'ime ya gaa n'èzí, na-ebelata ọnụ ọgụgụ esemokwu n'etiti eriri na yarns, si otú ahụ na-amụba mmegharị ha. Ya mere, mgbe akwa akwa akwa akwa, yarn na-adị mfe ikpokọta ma enwere ọtụtụ yarn ijikọ aka na-ebu ike ịdọka, na-ebute mmụba dị ukwuu na ndọka na ike mgbaji.
Ngwaahịa anyị
Mmanụ silicone anyị nwere ike nweta nsonaazụ dị mma na ajị anụ, dị ka ire ụtọ, ịdị nro, ịdị nro dị ukwuu, na ndị ọzọ. Anyị nwere ngwaahịa na ihe ngwọta kwekọrọ, ma nabata onye ọ bụla ka ọ gbanwee ihe nlele.
