E like me kā mākou e ʻike ai, manaʻo ʻia nā hale e loaʻa ke ola lawelawe ma kahi o 50 mau makahiki. No laila, pono e loaʻa i nā mea i hoʻohana ʻia ke ola lawelawe lōʻihi. Ua hoʻohana nui ʻia ʻo Silicone sealant ma ke kahua o ke kūkulu ʻana i ka wai a me ka sila ʻana ma muli o kona kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ke kū ʻana o ka wā kahiko, a me nā waiwai paʻa maikaʻi. Eia nō naʻe, ma hope o kekahi manawa ma hope o ke kūkulu ʻana, ua lilo ka discoloration o ka silikoni sealant i pilikia pinepine, e waiho ana i nā "laina" ma nā hale.
No ke aha e hoʻololi ai ke kala silicone ma hope o ka hoʻohana ʻana?
Nui nā kumu no ka wehe ʻana o ka ʻāpana a i ʻole ka pau ʻana o ka silicone tunnel sealant a i ʻole ke aniani glue, ʻoi loa ma nā ʻano aʻe:
1. ʻAʻole hiki ke hoʻohana pū ʻia nā mea hoʻopaʻa paʻa like ʻole ʻAʻole hiki ke hoʻohana pū ʻia nā sealant acid, nā mea hoʻopaʻa waiʻona kūʻokoʻa, a me nā sealants neutral oxime, no ka mea hiki iā lākou ke hoʻopili i kekahi i kekahi a hoʻoneʻe i ke kala. Hiki i nā mea hoʻopaʻa aniani waiʻona ke lilo i melemele nā mea hoʻopaʻa oxime, a ʻo ka hoʻohana pū ʻana i nā sila aniani hoʻokumu ʻia o ka oxime a me ke kūpaʻa ʻole e hiki ke hoʻomelemele.
ʻO nā molekala i hoʻokuʻu ʻia i ka wā o ka mālama ʻana i nā mea hoʻopaʻa ʻano oxime neutral, -C=N-OH, hiki ke hana me nā waikawa e hana i nā pūʻulu amino, i maʻalahi ʻia e ka oxygen i ka lewa e hana i nā mea kala, e alakaʻi ana i ka discoloration o ka sealant.
2. Hoʻopili me ka lāʻau a me nā mea ʻē aʻe
Hiki ke melemele nā mea hoʻopaʻa silikoni i ka wā e pili pono ai me kekahi mau ʻano lāʻau lapaʻau, e like me ka pulupulu maoli, ka pulupulu neoprene, a me ka pulupulu EPDM. Hoʻohana nui ʻia kēia mau ʻōpala i nā paia pale a me nā puka makani / puka ma ke ʻano he mau ʻōpala, gaskets, a me nā mea ʻē aʻe. Hōʻike ʻia kēia wehe ʻana e ka ʻole, me nā ʻāpana wale nō e pili pono ana me ka pahu e huli melemele ʻoiai ʻaʻole i hoʻopilikia ʻia nā wahi ʻē aʻe.
3. Hiki ke ho'ololi 'ia ka sealant ma muli o ka ho'onui 'ana
Ua kuhi hewa pinepine ʻia kēia ʻano i ka nalowale o ka waihoʻoluʻu o ka sealant, hiki ke kumu ʻia e nā kumu maʻamau ʻekolu.
1) Ua ʻoi aku ka nui o ka sealant i hoʻohana ʻia ma mua o kona hiki ke hoʻoneʻe ʻia a ua hoʻolōʻihi ʻia ka hui.
2) ʻO ka mānoanoa o ka sealant ma kekahi mau wahi he lahilahi loa, e hopena i ka hoʻololi ʻana o ke kala ma ia mau wahi.
4. ʻO ka wehe ʻana o ka sealant hiki ke hana ʻia e nā kumu kaiapuni.
ʻOi aku ka maʻamau o kēia ʻano discoloration i ka neutral oxime-type sealants, a ʻo ke kumu nui o ka wehe ʻana ʻo ia ka loaʻa ʻana o nā mea waikawa i ka lewa. Nui nā kumu o nā meaʻawaʻawa i ka lewa, e like me ka ho'ōla ʻana i ka silikoni sealant acidic, nā uhi acrylic i hoʻohana ʻia i ke kūkulu ʻana, nā kiʻekiʻe o ka sulfur dioxide i ka lewa i ka wā hoʻoilo ma nā ʻāpana ʻākau, ke puhi ʻana i ka ʻōpala palaka, ka asphalt ahi, a me nā mea hou aku. Hiki i kēia mau mea ʻakika a pau i ka lewa ke hoʻoheheʻe i nā mea hoʻopaʻa ʻano oxime.
Pehea e pale aku ai i ka discoloration o ka silicone sealant?
1) Ma mua o ke kūkulu ʻia ʻana, e hana i kahi hoʻāʻo hoʻohālikelike i nā mea e pili ana me ka sealant e hōʻoia i ka hoʻohālikelike ʻana ma waena o nā mea, a i ʻole e koho i nā mea hoʻohui kūpono, e like me ke koho ʻana i nā huahana rubber silicone ma mua o nā huahana lāʻau e hōʻemi i ka hiki ke melemele.
2) I ka wā o ke kūkulu ʻia ʻana, ʻaʻole pono e hoʻopili ʻia ka sealant neutral me ka sealant acid. ʻO nā mea amine i hana ʻia e ka decomposition o ka mea hoʻopaʻa kūʻokoʻa ma hope o ka loaʻa ʻana o ka waikawa e oxidize i ka lewa a hoʻoneʻe i ka ʻili.
3) Hōʻalo i ka hoʻopili ʻana a i ʻole ka ʻike ʻana o ka mea hoʻopaʻa i nā wahi ʻino e like me nā waikawa a me nā alkali.
4) Loaʻa ka discoloration i nā huahana ʻulaʻula, keʻokeʻo, a me ka ʻike. ʻO ke koho ʻana i nā sealants ʻeleʻele a ʻeleʻele paha hiki ke hōʻemi i ka pilikia o ka wehe ʻana.
5) E koho i nā sealants me ka maikaʻi i hōʻoia ʻia a me ka inoa inoa maikaʻi-JUNBOND.
