Hoʻohana maikaʻi ʻia ʻo HP-669 i loko o ka ʻoihana lāʻau lapaʻau ma ke ʻano he mea hoʻohui hui ʻelua poly sulfur silane.
Hiki ke hoʻohana ʻia ʻo HP-669 i loko o ka ʻōnaehana vulcanized rubber me nā mea hoʻopihapiha e like me ka silica, fiberglass, talc pauka, mica pauka a me ka pālolo e like me ka mea hoʻoikaika.Hiki iā ia ke hoʻomaikaʻi i ka hoʻoikaika ʻana i nā waiwai o nā mea hoʻopihapiha a me nā waiwai pale abrasive.
He kūpono ia e hoʻohana ʻia ma ke ʻano he mea hoʻohui hoʻohui-vulcanizing agent a me ka mea hoʻoulu i nā polymers e like me NR, IR, SBR, BR, NBR a me EPDM.
I ke kaʻina hana o ka vulcanization, ka crosslinking rate o ka poly-sulfur alkyl like me ka deoxidizing rate o ka sulfur, no laila, hana ia e pale aku i ka deoxidization o ka vulcanization, a laila hoʻomaikaʻi i ka ikaika bending waiwai e like me ka wela kūkulu a me nā māwae hoʻonui .The eha sulfur hiki i nā atom ke hana ma ke ʻano he mea hoʻoikaika no ka vulcanization.
I nā kūlana ikaika a paʻa, hoʻohana ʻia ia no ka hana ʻana i kēia mau huahana lāʻau lapaʻau: kaʻa, hose, ʻōwili pahu, kāʻei, kaula, kāmaʻa a me nā huahana hoʻokumu mechanical.Hiki iā ia ke hoʻomaikaʻi i ke kūpaʻa abrasive, ka ʻoki ʻana i ke kūʻē a me ke kūpaʻa puʻuwai, e hōʻemi i ka nalowale o ka hysteresis a me ka hygroscopicity, hoʻomaikaʻi i nā waiwai mechanical a me ka adhesive, a hoʻonui i ka hana ʻelemakule wela, modulus a flex life.
E hoʻohui i ka mea hoʻohui sulfur-silane i ka ʻoihana o ke kaila kaila, ʻaʻole ia e hoʻohaʻahaʻa wale i ka pilikia o ka puncture e like me ke kiʻekiʻe o ka mahana e holo ana ma ke ala kiʻekiʻe a i ʻole ka lōʻihi o ka manawa, akā e hōʻemi hoʻi i ka pale ʻana o ke kaila, a laila hoʻemi i ka ʻai ʻana o ka ʻaila. ka nui o ka hoʻokuʻu ʻana o CO2 e like me ka mālama ʻana i ke kaiapuni o ka hōʻemi kalapona.

Pūʻolo a me ka waiho ʻana

1. Pūʻolo: 25kg a i ʻole 200 kg a i ʻole 1000kg i ka pahu plastik.
2. Mālama ʻia i ka sila: E mālama i nā wahi anuanu, maloʻo a me ka makani maikaʻi.
3. Ke ola mālama: ʻoi aku ka lōʻihi ma mua o ʻelua mau makahiki ma nā kūlana mālama maʻamau.
