ʻO Shanghai Huayingtong E-commerce Co., Ltd. kekahi o nā alakaʻiphenolic resinnā mea hoʻolako ma Kina a me kahi ʻoihanaphenolic resin manufacturer. Welcome to purchasephenolic resin from our factory.pls contact tom :service@skychemwin.com

Inoa Huahana：phenolic resin

Hōʻano molekala:

Helu CAS:9003-35-4

Huahana molecular structure：

Na Waiwai Kemika:

Hoʻomākaukau ʻia ka resin Phenol-formaldehyde penei:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
Hoʻokahi-ʻanuʻu Resins. He kiʻekiʻe ka lakio o ka formaldehyde i ka phenol e hiki ai i ke kaʻina hana thermosetting ke hana me ka hoʻohui ʻole o nā kumu kumu o nā loulou keʻa.
ʻElua mau ʻāpana Resins. He haʻahaʻa ka ratio o ka formaldehyde i ka phenol e pale ai i ka hopena thermosetting mai ka wā e hana ʻia ai ka resin. I kēia manawa ua kapa ʻia ka resin novolac resin. A laila, hoʻokomo ʻia ka hexamethylenetetramine i loko o ka mea e hana ai ma ke ʻano he kumu o nā loulou kemika i ka wā o ka hana ʻana (a me ka hoʻololi ʻana i ka thermoset a i ʻole ke kūlana hoʻōla).

Nā ʻano o nā resins phenolic:

1、Phenolic Resins no nā mea pili
2、Papa kaila resins
3、Phenolic resins no nā abrasives i hoʻopaʻa ʻia
4、Phenolic resins no ka ʻohe a me nā mea lāʻau
5、Phenolic Resins no ka ʻaila ʻaila
6、Phenolic resins no ka hana ʻana i nā pūhui
7、Phenolic resins no nā mea impregnated
8、Resins no ka ʻoihana uhi
9、Phenolic resins no ka wela wela
10、Phenolic resins no nā abrasive i uhi ʻia

Noi:

Hoʻohana ʻia nā resins Phenolic no nā ʻāpana kūʻai haʻahaʻa e koi ana i nā waiwai insulating uila maikaʻi, pale ʻana i ka wela, a i ʻole ke kūʻē kemika. ʻO ka maʻamau o ke ola o kēia resin ma kahi o 1 mahina ma 21.1 ° C. Hiki ke hoʻonui ʻia ma ka mālama ʻana i loko o ka friji ma 1.6 a 10 ° C. ʻO ka hoʻololi ʻana i ka catalyst (e like me ka mānoanoa o ka hoʻolei) a me ka hoʻonui ʻana i ka mahana hoʻōla i 93 ° C e hoʻololi i ka manawa hoʻōla mai ka lōʻihi o 8 mau hola a hiki i ka 15 min.
Loaʻa kekahi shrinkage i ka hoʻolei ʻana (0.012 a 0.6 mm / mm), e pili ana i ka nui o ka hoʻopiha, ka nui o ka catalyst, a me ke ʻano o ka hoʻōla. ʻO nā pōʻai hoʻōla ʻoi aku ka wikiwiki o ka emi ʻana. No ka mea hiki ke hoʻolōʻihi ʻia ka pōʻaiapuni lapaʻau, hoʻohana ʻia nā phenolics i nā hana pōkole.
Hoʻopau maʻalahi ʻia nā ʻāpana phenolic mai ka mold inā hoʻohana ʻia nā mea hoʻokaʻawale i ʻōlelo ʻia e ka mea hoʻolako. Hoʻomaikaʻi ʻo Posturing i nā waiwai kumu o ka hoʻolei ʻana.
