Mastic BPM-3 a me BPM-4. waiwai hui

Nā waiwai a me nā hiʻohiʻona maikaʻi o nā mastics rubber-bitumen

ʻO ka mastic, i hoʻomākaukau ʻia ma ke kumu o ka lāʻau a me ka bitumen, kahi uhi hoʻokahi-hui, kahi mea pale ʻole i ka makū. Hoʻokumu ia i kahi papa hoʻomau i loko o ia, ʻoiai ke ʻano o ka hoʻololi ʻana o ka wela o waho, mālama ʻia kahi ʻano wela paʻa, kahi e hoʻolohi nui ai i nā kaʻina o ka corrosion a me ka pala o nā mea metala.

ʻO nā mastics Rubber-bitumen no ka hui i kapa ʻia ʻo "cold" mastics, i hoʻopili ʻia i nā ʻāpana i hoʻopaʻa ʻia o ke kaʻa ma hope o ka hoʻomaʻamaʻa ʻana, akā ma nā lumi wela (ua manaʻo ʻia ka hoʻomehana ʻana e hoʻemi iki i ka viscosity o ka haku mele, no ka maʻalahi. o ka hana pū me ia). Eia kekahi, hana kēlā me kēia ʻāpana i nā hana i wehewehe pono ʻia. Hoʻonui ka Rubber i ka elasticity o ka mastic a me kona kūpaʻa ʻana i ke kulou ʻana i ka wā o ka ʻoi ʻana a i ʻole ka haʻalulu, a ʻo ka bitumen ke kōkua i ka hydrophobicity o ka mastic a me kona kūʻē ʻana i nā kaiapuni kemika (acid a me alkalis).

Ma muli o nā makahiki o nā kumu bituminous a nalowale kona elasticity, hoʻohui ʻia nā pūhui polymeric i ka mastic, kahi e hoʻonui ai i ka wahi palupalu. Pono kēia i mea e hoʻohana ai i ka BPM series rubber-bitumen mastics a puni ka makahiki.

Nā hiʻohiʻona hana o nā haku mele e noʻonoʻo ʻia:

Kaumaha mastic	ʻO ka mahana palupalu, ° С	Elongation plasticity, mm	ʻO ka hoʻolōʻihi ʻia i ka hoʻomaka ʻana o ka haki ʻana, %	Ka wela noi, °С
BPM-3	50	3 ... 5	60	10 ... 30
BPM-4	60	4 ... 8	100	5 ... 30

Mastic BPM-3

Ke hoʻohana ʻia i nā ʻili metala o ke kaʻa, hana ka haku mele i nā hana penei:

• Pale i ke kila mai ka pala.
• Hoʻemi i ka pae walaʻau i loko o ke keʻena.
• Hana i ka pale mechanical o ka lalo mai nā paʻakai like ʻole, nā pōhaku ʻokiʻoki, ʻiliʻili.
• Kōkua i ka hoʻomāmā ʻana i nā haʻalulu.

ʻO ka loaʻa ʻana o ka ʻōpala maikaʻi i loko o ka haku mele e hōʻoia i ka lawa o ka elasticity o ka uhi, i mālama ʻia ma nā haʻahaʻa haʻahaʻa (a hiki i -15 ... -20).⁰C).

Hoʻokomo ʻia nā haku mele Aluminosilicate i ka haku mele BPM-3 mastic, kahi e pale ai i nā ʻāpana kino o waho mai nā ukana ikaika. I ka manawa like, hoʻomaikaʻi ʻia ka pale ʻana o ka mīkini. Hāʻawi ka mea bituminous i ka hoʻomau pono o ka uhi a hōʻemi i ka wahi o nā wahi manuahi.

Hiki ke puhi ʻia ka mastic, no laila ua ʻōlelo ʻia e hana pū me ia ma nā wahi i hoʻoluʻu maikaʻi ʻia, ma kahi o nā kumu o ka lapalapa ākea. Ma mua o ka hoʻohana ʻana i ka mastic e hoʻomehana ʻia i loko o kahi ʻauʻau wai a i kahi lumi mahana. Mākaukau ka haku mele no ka hoʻohana ʻana i ka wā he ʻeleʻele like ʻole.

Mastic BPM-4

ʻO ka BPM-4 kahi kumu hoʻomaikaʻi o BPM-3 mastic. Ma keʻano kūikawā, aia kekahi mau mea e hoʻonui ai i ka modulus o ka elasticity o ka mea, kahi hopena maikaʻi i ka lōʻihi o ka uhi.

Eia kekahi, ʻike ʻia ka BPM-4 rubber-bitumen mastic e:

• ʻO ka loaʻa ʻana o nā aila ʻaila amine, e hāʻawi ana i kahi hopena anti-corrosion hou aʻe e mau ana no ka manawa lōʻihi.
• Hoʻonui ʻia ka elasticity o ka ʻili i mālama ʻia, he mea koʻikoʻi loa ia no nā kaʻa i hana ʻia ma nā alanui ʻino.
• Hoʻonui ʻia ka ʻoluʻolu o ke kaiapuni i ka wā e hoʻohana ai, no ka mea, ʻaʻohe ona mea e hoʻonāukiuki i ka ʻōnaehana hanu.

ʻO nā ʻāpana hana i koe e pili ana i nā hiki o ka BPM-3 mastic.

Hoʻokō ʻia ka hana ʻana o ka rubber-bitumen mastics grade BPM-3 a me BPM-4 e like me nā koi ʻenehana o GOST 30693-2000.

Nā mea hoʻohana

Hōʻike ka hapa nui o nā loiloi i kēia mau hiʻohiʻona o ka hoʻohana ʻana i kēia mau ʻano mastics:

1. ʻO ka makemake o ka hoʻohana ʻana i nā thinners, no ka mea ma ka mokuʻāina mua (ʻoiai ma hope o ka palupalu ʻana o ka wela) he paʻakikī ke hoʻohana ʻana i nā mastics, ʻoi aku hoʻi ma nā papa me kahi hoʻonohonoho paʻakikī. Manaʻo ʻia ʻo Gasoline Kalosh, kerosene, toluene e like me ka diluting compound. Eia naʻe, ʻaʻole pono ka nui o ka thinner ma mua o 15% o ka leo mastic kumu.
2. Hoʻomaopopo kekahi mau loiloi i ka ʻoiaʻiʻo o ka ʻelemakule kino o ka uhi i mālama ʻia me BPM-3, ka mea e hakakā nei nā mea nona nā kaʻa me ka hoʻokomo ʻana i nā plasticizers i ka mastic. I kēia mana, hiki iā ʻoe ke hoʻohana i ka aila mīkini kānana.
3. Ke hoʻohālikelike ʻia i ka BPM-3, hiki ke hoʻopili ʻia ka BPM-4 mastic i hoʻokahi papa, akā ma mua o ia mea e ʻōlelo ʻia e hoʻomaʻemaʻe a hoʻomaʻemaʻe i ka ʻili, a me ka hoʻopili ʻana i kahi primer phosphate.
4. ʻAʻole like me kekahi mau huahana like - no ka laʻana, Kordon anticorrosive - Nizhny Novgorod mastics ʻaʻole e haki i nā haʻahaʻa haʻahaʻa haʻahaʻa.

Manaʻo nā mea hoʻohana i ka "aloha" o nā haku mele ʻelua he hiʻohiʻona maikaʻi, e ʻae ai i ka hoʻohana ʻana i nā huahana like ʻole.
