Ngwa nke HPMC (hydroxypropyl methylcellulose) na silicone sealants nwere ọtụtụ uru, ọkachasị n'ọhịa metụtara batrị batrị. HPMC n'onwe ya bụ cellulose ether gbanwetụrụ na mmiri siri ike na ihe na-eme ka ọ dị ike, ya mere a na-eji ya eme ihe na ụlọ ọrụ mmepụta ihe, ihe ụlọ na batrị batrị.
1. Magburu onwe thickening arụmọrụ
HPMC nwere ike ndim ike, nke na-enyere ya aka n'ụzọ dị irè melite rheological Njirimara nke silicone sealants. Site n'ịgbakwunye HPMC na usoro ahụ, colloid nwere ike ijikwa oke mmiri na viscosity ya nke ọma, na-eme ka ọnọdụ ziri ezi na ọdịdị kwụsiri ike n'oge eji. Nke a dị mkpa karịsịa maka batrị batrị, nke nwere ike hụ na a na-ekesa ihe mkpuchi ahụ n'otu n'otu na nkwonkwo nke akụrụngwa batrị, na-ebelata ihe na-adịghị mkpa na ntanye.
2. Ezigbo ihe na-emepụta ihe nkiri
HPMC nwere ezigbo ihe na-emepụta ihe nkiri. Mgbe a na-eji ya na silicone sealants, ọ nwere ike inyere colloid aka ịmepụta uwe na ihe nchebe siri ike mgbe a gwọrọ ya. Igwe ihe nkiri a abụghị naanị nwere njirimara nke mmiri na-adịghị na mmiri na mmiri, ma na-egbochikwa mmetụta nke gburugburu ebe obibi na ihe dị n'ime batrị ahụ. Maka sistemu batrị nwere mmetụta dị ka batrị lithium-ion, ọnụnọ nke ihe nkiri nchebe nwere ike imeziwanye ndụ na nkwụsi ike ha.
3. Mmanya adhesion
N'ihe mkpuchi batrị, ntinye nke ihe mkpuchi ahụ dị oke mkpa iji hụ na ikuku batrị dị. HPMC nwere ike ịkwalite nchikota nke silicone sealants, na-enye ha ohere ijikọ nke ọma na ihe dị iche iche (gụnyere plastik, ọla, iko, wdg). Ngwongwo a na-eme ka o doo anya na ihe mkpuchi batrị nwere ike ịnọgidesi ike ruo ogologo oge, na-egbochi ihe ndị dị n'èzí dị ka ikuku na mmiri ịbanye na batrị ma mebie arụmọrụ batrị.
4. Mmelite okpomọkụ na-eguzogide
HPMC nwere ezigbo nkwụsi ike nke okpomọkụ na gburugburu ebe okpomọkụ dị elu, ya mere silicone sealants na HPMC gbakwunyere nwere ike idowe ihe eji arụ ọrụ ha na akara akara n'ime oke okpomọkụ dị elu. Maka batrị ndị chọrọ ịrụ ọrụ na gburugburu okpomọkụ dị elu ruo ogologo oge (dịka batrị ụgbọ ala eletrik, batrị nchekwa ike anyanwụ, wdg), nkwụsị okpomọkụ a dị mkpa karịsịa ma nwee ike melite nchekwa na ndụ ọrụ batrị.
5. Ọmarịcha ihe owuwu ụlọ
Ngwongwo na-eme ka mmanụ aṅụ nke HPMC na-eme ka silicone sealants dị mfe ịrụ ọrụ n'oge a na-ewu. Colloid nwere mmiri na-agafeghị oke ma enwere ike itinye ya ngwa ngwa n'akụkụ dị iche iche nke batrị na-enweghị ihe isi ike ụlọ n'ihi oke mmiri na-asọ. Nke a ọ bụghị naanị na-eme ka nrụpụta ihe nkedo dị mma, ma na-ebelata ihe mkpofu ihe n'oge usoro ihe owuwu.
6. Magburu onwe ihu igwe na-eguzogide
HPMC na-enye silicone sealant ezigbo nguzogide ihu igwe. Mgbe ekpughere ya na ihe ndị metụtara gburugburu ebe obibi dị ka ụzarị ultraviolet, oxygen, na uzuoku mmiri ruo ogologo oge, ihe mkpuchi ahụ ka nwere ike ịnọgide na-agbanwe ya, nrapado na ihe anụ ahụ. Maka akụrụngwa arụ ọrụ ogologo oge dị ka batrị, nguzogide ihu igwe a na-eme ka a mata na ihe mkpuchi n'ime batrị agaghị ada n'ihi mgbanwe gburugburu ebe obibi, si otú ahụ na-eme ka ntụkwasị obi zuru ezu nke batrị ahụ dịkwuo elu.
7. Nkwụsi ike nke kemịkalụ na nchedo gburugburu ebe obibi
HPMC bụ ihe kwụsiri ike nke nwere akụrụngwa kemịkalụ, nke nwere ike igbochi silicone sealant nke ọma imeghachi omume ọjọọ na kemịkalụ mpụga n'oge eji. N'otu oge ahụ, HPMC n'onwe ya bụ ihe okike nwere ezigbo biodegradaability. Ya mere, e jiri ya tụnyere ihe mgbakwunye kemịkalụ ndị ọzọ, ọ na-enwechaghị mmetụta na gburugburu ebe obibi ma na-emezu ihe ndị a chọrọ nke ụlọ ọrụ ọgbara ọhụrụ maka ihe ndị na-eme ka gburugburu ebe obibi.
8. Belata mgbasa mmiri
HPMC nwere ezigbo njide mmiri, nke pụtara na ọ nwere ike belata oke mmiri na-ekesa na mkpuchi. Maka akara batrị, njirimara a nwere ike igbochi ihe dị n'ime batrị ahụ site na ikuku mmiri na-emebi, si otú a na-ebelata ihe ize ndụ nke ọdịda mmeghachi omume electrochemical ma ọ bụ obere sekit batrị kpatara site na ntinye mmiri.
9. Mee ka ike nke sealants dịkwuo mma
Ọnụnọ nke HPMC nwekwara ike ịkwalite ngbanwe nke silicone sealants nke ọma, na-enye ha ohere idobe akara ha na iguzosi ike n'ezi ihe mgbe ọ na-emetụta ya site na ịma jijiji mpụga, nrụgide n'ibu, ma ọ bụ mgbasawanye ọkụ. Nke a dị ezigbo mkpa maka batrị ekwentị mkpanaaka ma ọ bụ batrị na-anọkarị na ọnọdụ ịma jijiji (dịka akụrụngwa ikuku na batrị ụgbọ ala), na-eme ka nkwụsi ike nke akụrụngwa na gburugburu ebe dị oke egwu.
10. Jikwaa ọsọ ihicha nke colloid
N'oge ihicha na ọgwụgwọ nke silicone sealants, HPMC nwere ike inye aka chịkwaa ọnụego nke evaporation mmiri, si otú na-ezere cracking ma ọ bụ na-ekwekọghị ọgwụgwọ nke kpatara oke ngwa ngwa ihicha nke colloid elu. Nke a dị oke mkpa maka nhazi batrị nke na-achọ ogologo oge ọgwụgwọ, nke nwere ike hụ na arụmọrụ akara na njirimara anụ ahụ nke ngwaahịa ikpeazụ.
Ngwa nke HPMC na silicone sealants nwere ọtụtụ uru dị ịrịba ama, ọkachasị n'ihe gbasara batrị batrị. Ọ bụghị naanị na ọ na-eme ka adhesion dịkwuo mma, ihe ndị na-emepụta ihe nkiri na nguzogide okpomọkụ nke sealant, kamakwa ọ na-enye nchebe ka mma maka batrị site n'ịkwalite ngbanwe ya, nkwụsị ihu igwe na ịrụ ọrụ ihe owuwu. N'otu oge ahụ, njirimara nchebe gburugburu ebe obibi nke HPMC na-emezu ihe achọrọ nke ụlọ ọrụ ọgbara ọhụrụ maka mmepe mmepe, ọ bụkwa ihe mgbakwunye dị mma na gburugburu ebe obibi. Site n'ichepụta usoro ezi uche na nhazi usoro, HPMC nwere ike inye aka mepụta silicone sealants dị elu, na-arụ ọrụ dị mkpa na njichi batrị, injinia ihe owuwu na mpaghara ndị ọzọ.
