Hoʻohālikelike ʻia me nā pena kaha alanui ʻē aʻe (wele wela, pena anu),pena kaha alanui elualoaʻa nā hiʻohiʻona kupaianaha penei:

ʻO ka manawa maloʻo e pili wale ana i ka mahana ambient, ka nui o ka lāʻau lapaʻau, a me nā mea ʻē aʻe, ʻaʻohe mea pili i ka mānoanoa o ke kiʻi uhi.ʻAe kēia i ka pena kaha alanui ʻelua e hoʻolālā ʻia i loko o nā kiʻi ʻoniʻoni mānoanoa a me nā māka alanui hana ʻē aʻe, e like me nā kaha ʻelua oscillating pō ua hoʻomanaʻo ʻia, nā kaha kiko, a pēlā aku;

ʻO ka hopena cross-linking i ke kaʻina hana kiʻi ʻoniʻoni e hoʻomaikaʻi nui i ka ikaika mechanical o ke kiʻi ʻoniʻoni, ka hoʻopili ʻana i ka ʻili o ke alanui a me ka ikaika hoʻopaʻa i ka mea noʻonoʻo;hiki ke hoʻohana ʻia kekahi mau ʻāpana ʻelua e hōʻailona ana i ke alanui ma nā alanui pulu ʻo Curing, no laila hiki iā ia ke hoʻoponopono i ke kūlana maikaʻi ʻole o ka pena kaha alanui i ka ua.

Ma kēia ala, loaʻa i nā hōʻailona ʻelua ʻāpana ko lākou pono ponoʻī i hoʻohālikelike ʻia me nā ʻano hōʻailona ʻē aʻe.Ma hope aʻe, e hōʻike aku wau iā ʻoe i nā hōʻailona maʻamau ʻelua a me kā lākou mau hiʻohiʻona.

Epoxy ʻelua ʻāpana hōʻailona

Hoʻohana maʻamau ʻia nā māka epoxy e huki i nā ʻāpana kala ʻole.Ma muli o ka liʻiliʻi o ka epoxy resin maka, ʻoi aku ka haʻahaʻa o ke kumu kūʻai o nā hōʻailona epoxy, akā ʻilihune kona haʻahaʻa haʻahaʻa haʻahaʻa.Pono e ho'ōla ʻia ka epoxy resin ma kahi mahana ma luna o 10 ° C.Inā haʻahaʻa loa, lōʻihi loa ka manawa hoʻōla.ʻOi aku ka manawa mālama ma mua o 8 mau hola ma kahi haʻahaʻa haʻahaʻa ma lalo o 10 ℃.ʻO kēia ka pilikia nui e hoʻopaʻa ana i ka hoʻohana ʻana i nā uhi epoxy resin mākaʻikaʻi alanui.ʻO ka lua, ʻano ʻilihune kona mau ʻelemakule māmā a noho i loko o nā molekala.Hoʻopau maʻalahi ka paʻa eter aromatic ma lalo o ka irradiation o ke kukui ultraviolet, a ʻilihune ka pale ʻana o ka wā o waho o ke kiʻi uhi.

ʻO ka mākaʻikaʻi polyurethane ʻelua

Hoʻohana pū ʻia nā kaha polyurethane ma nā papa waihoʻoluʻu.Ua like kona kaʻina hana me ka epoxy.ʻAʻole ia e uhi ʻia ma hope o ke kūkulu ʻana, akā lōʻihi loa ka manawa hoʻōla, ʻoi aku ma mua o 4-8 mau hola.Loaʻa i nā pale polyurethane kekahi flammability a me nā mea ʻawaʻawa, kahi e hoʻopilikia ai i ke olakino a me ka palekana o nā limahana hana.I ka manawa like, ʻokoʻa loa ka ʻike paʻa o ka polyurethane raw material ma muli o nā ʻano hana like ʻole, a ʻo ka hui solvent maʻamau ma waena o 3% a me 15%, ka hopena i nā uhi paʻa.ʻOi aku ka ʻokoʻa o ke kumu kūʻai i kēlā me kēia tona ma mua o 10,000 yuan, a ʻoi aku ka haunaele o ka mākeke.

ʻO ka hōʻailona ʻelua ʻāpana polyurea

ʻO ka mākaʻikaʻi polyurea he mea elastic i hana ʻia e ka hopena o ka ʻāpana isocyanate A a me ka mea hui cyano B. Hoʻohana maʻamau ia ma nā paepae kala.Ho'ōla koke ke kiʻi ʻoniʻoni polyurea, a hiki ke hana ʻia ke kiʻiʻoniʻoni i 50 kekona no ka poʻe hele wāwae, hiki ke hoʻopōkole loa i ka manawa hana., Akā, ʻoi aku ka wikiwiki o ka pane ʻana, kahi e pilikia ai ke kūkulu ʻana.Hoʻohana nui ʻia ia no ka pulupulu ʻana a koi ʻia ka ʻenehana hoʻoheheʻe kiʻekiʻe.ʻO ka hemahema i maopopo loa ʻo ia ka pipiʻi a me ke kumu kūʻai.

MMA kaha ʻelua ʻāpana

ʻAʻole hiki i ka māka ʻelua ʻāpana MMA ke kaha kiʻi i nā alanui kala wale nō, akā i nā laina melemele a me ke keʻokeʻo.Loaʻa iā ia kahi ākea o nā noi.Loaʻa iā ia nā pono penei:

1. He wikiwiki loa ka maloo ana.ʻO ka manawa maʻamau he 3 ~ 10min, a e hoʻihoʻi ʻia ke alanui i ke kaʻa i loko o kahi manawa pōkole o ke kūkulu ʻana.ʻOiai ma kahi haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke hoʻonui ʻia ka nui o ka lāʻau lapaʻau e like me ke ʻano o ka resin, a hiki ke hoʻokō ʻia ka curing ma 5 ° C no 15 ~ 30min.

2. Hana maikaʻi loa.

① Hoʻololi maikaʻi.Hiki i ka maʻalahi kū hoʻokahi o ka methyl methacrylate ke pale i ka hiki ʻana mai o ka haki ʻana o ke kiʻi ʻoniʻoni.

②Hoʻopili maikaʻi.ʻO ka polymer ikaika haʻahaʻa haʻahaʻa haʻahaʻa hiki ke hoʻopili maikaʻi ʻia i nā capillaries e waiho ana ma ke kahua papahele, a hiki ke hoʻoponopono i ka pilikia ʻaʻole hiki ke hoʻohui maʻalahi ʻia nā pena kaha ʻē aʻe me nā papa pōhaku sima.

③Super abrasion kū'ē.ʻO ka hopena polymerization o ke kaʻina hana kiʻiʻoniʻoni e hoʻokumu i kahi ʻano molecular network, kahi e hoʻohui pū ai i nā ʻāpana like ʻole o ka uhi ʻana i loko o kahi paʻa.

④Maikaʻi ke kū i ka wā.ʻAʻole hana ka mākaʻikaʻi i ka haʻahaʻa haʻahaʻa haʻahaʻa a i ʻole ka palupalu kiʻekiʻe, a aneane ʻaʻohe ʻelemakule i ka wā hoʻohana;ʻO nā ʻāpana ʻelua e hana i kahi mole pūnaewele hou ma hope o ka polymerization, ʻo ia ka polymer kaumaha molekala nui, a ʻaʻohe mea paʻa molekala hou.

3. ʻO nā hiʻohiʻona palekana kaiapuni kiʻekiʻe.

E hoʻopau ka solvent volatilization i ka papa ozone lewa a hoʻopilikia i nā pilikia kūlohelohe.Hoʻohālikelike ʻia me ka pena kaha alanui hoʻokahi, hoʻōla ʻia ka pena acrylic ʻelua e ka polymerization kemika, ma mua o ka volatilization kino a me ka maloʻo.Aneane ʻaʻohe mea hoʻoheheʻe i loko o ka ʻōnaehana, he liʻiliʻi wale ka nui o ka monomer volatilization i hana ʻia i ka wā o ke kūkulu ʻana (ka hoʻoulu ʻana, ka uhi ʻana), a ʻoi aku ka haʻahaʻa o ka hoʻokuʻu ʻana o ka solvent ma mua o ka peʻa makaʻala alanui.
