1. Ke kū'ē i ka ho'āʻo loaʻa kaumaha
Hiki ke hoʻohālikelike ʻia ka huahana i hoʻopau ʻia, hoʻomoʻi ʻia i loko o hoʻokahi a i ʻole kekahi mau media i koho ʻia, ke kaupaona ʻia ma hope o kekahi mahana a me ka manawa, a hiki ke hoʻohālikelike ʻia ke ʻano o ka mea e like me ka loli kaumaha a me ka loli paʻakikī.
No ka laʻana, i loko o 100 degere ka aila no 24 hola, NBR, fluorine rubber, ECO, CR i ka liʻiliʻi liʻiliʻi i loko o ka maikaʻi a me ka paakiki, oiai NR, EPDM, SBR oi ma mua o papalua i ke kaumaha a me ka hoʻololi i ka paakiki nui, a me ka leo hoonui. maopopo.
2. Hot ea elemakule hoao
E lawe i nā laʻana mai nā huahana i hoʻopau ʻia, e waiho i loko o ka pahu ʻelemakule no hoʻokahi lā, a nānā i ke ʻano ma hope o ka ʻelemakule.Hiki ke hoʻonui mālie ʻia ka ʻelemakule.No ka laʻana, e palupalu ʻo CR, NR, a me SBR ma 150 degere, ʻoiai ʻo NBR EPDM e lohi mau.Ke piʻi ka mahana i 180 degere, e palupalu ka NBR maʻamau;a ʻo ka HNBR hoʻi e palupalu ma 230 degere, a ʻo ka fluorine rubber a me ka silicone he mau elasticity maikaʻi.
3. Keʻano puhi ahi
E lawe i kahi hāpana liʻiliʻi a puhi i ka lewa.nānā i ke ʻano.
ʻO ka ʻōlelo maʻamau, ʻaʻohe ahi ka fluorine rubber, CR, CSM, a inā paha e ʻā ana ka lapalapa, ʻoi aku ka liʻiliʻi ma mua o ka NR maʻamau a me ka EPDM.ʻOiaʻiʻo, inā mākou e nānā pono, ʻo ke ʻano o ka puhi ʻana, ka waihoʻoluʻu, a me ka ʻala e hāʻawi iā mākou i ka ʻike he nui.No ka laʻana, ke hui pū ʻia ʻo NBR/PVC me ke kāpili, i ka wā e loaʻa ai kahi kumu ahi, paʻi ke ahi a me he wai lā.Pono e hoʻomaopopo ʻia i kekahi manawa e hoʻopau ʻia ke kolu pale ahi akā ʻaʻole halogen i ke ahi, pono e hoʻohālikelike ʻia e nā ala ʻē aʻe.
4. Ana ana i ka umekaumaha kiko
E hoʻohana i ka unahi uila a i ʻole ke kaulike analytical, pololei i ka 0.01 grams, me kahi aniani wai a me kahi lauoho.
ʻO ka mea maʻamau, ʻo ka fluorine rubber ka nui o ka gravity kikoʻī, ma luna o 1.8, a ʻo ka hapa nui o nā huahana CR ECO he hapa nui ma luna o 1.3.Hiki ke noʻonoʻo ʻia kēia mau glues.
5. Keʻano wela haʻahaʻa
E lawe i kahi laʻana mai ka huahana i hoʻopau ʻia a hoʻohana i ka hau maloʻo a me ka waiʻona e hana i kahi ʻano cryogenic kūpono.E hoʻokuʻu i ka hāpana ma kahi haʻahaʻa haʻahaʻa no 2-5 mau minuke, e ʻike i ka palupalu a me ka paʻakikī i ka wela i koho ʻia.No ka laʻana, ma -40 degere, ua hoʻohālikelike ʻia ka wela kiʻekiʻe a me ka pale ʻaila silica gel a me ka fluorine rubber, a ʻoi aku ka palupalu o ka silica gel.
