Mastic BPM-3 na BPM-4. Njirimara ngwakọta

Ngwongwo na njirimara dị mma nke rubber-bitumen mastics

Mastic, nke a kwadebere na ndabere nke rọba na bitumen, bụ ihe mkpuchi nke otu akụkụ, nke bụ ihe mgbochi na-apụghị imeri emeri na mmiri. Ọ na-etolite oyi akwa na-aga n'ihu nke, n'agbanyeghị mgbanwe okpomọkụ nke mpụga, a na-edobe ọchịchị okpomọkụ siri ike, nke na-ebelata usoro nke corrosion na ire ere nke ihe ígwè.

Rubber-bitumen mastics so n'òtù ndị a na-akpọ "oyi" mastics, nke a na-etinye n'akụkụ akụkụ nke ụgbọ ala ahụ mgbe ọ na-ekpo ọkụ, ma na okpomọkụ nke ụlọ (ekpo ọkụ bụ nanị iji belata viscosity nke ihe mejupụtara, maka ịdị mfe. na-arụ ọrụ na ya). Na mgbakwunye, akụkụ nke ọ bụla na-arụ ọrụ akọwapụtara nke ọma. Rubber na-abawanye ngbanwe nke mastic na nguzogide ya na-ehulata n'oge ihe ọkụkụ dị nkọ ma ọ bụ ihe mgbagwoju anya, na bitumen na-enye aka na hydrophobicity nke mastic na nguzogide ya na gburugburu ebe ndị na-eme ihe ike (acids na alkalis).

Ebe ọ bụ na ntọala ọ bụla bituminous na-akawanye oge ma na-efunahụ ike ya, ogige polymeric nke na-eme ka ebe dị nro ga-agbakwunye na mastic. Nke a dị mkpa iji jiri usoro BPM rubber-bitumen mastics mee ihe n'afọ niile.

Njirimara arụmọrụ nke ihe ndị a na-atụle:

Mastic BPM-3

Mgbe etinyere ya na mbara igwe nke ụgbọ ala, ihe mejupụtara ya na-arụ ọrụ ndị a:

• Na-echebe ígwè pụọ na corrosion.
• Na-ebelata ọkwa mkpọtụ n'ime ụlọ.
• Na-arụ ọrụ nchebe nke ala site na nnu dị iche iche, nkume a gbajiri agbaji, gravel.
• Na-enyere aka belata ịma jijiji.

Ọnụnọ nke rọba gbasasịrị nke ọma na ihe mejupụtara na-eme ka ọ dịkwuo mma nke mkpuchi, nke a na-edobe ọbụna na obere okpomọkụ (ruo -15 ... -20).⁰NA).

A na-ewebata ihe mejupụtara aluminosilicate n'ime mastic BPM-3, ọnụnọ ya na-echebe akụkụ ahụ dịpụrụ adịpụ site na ibu dị ike. N'otu oge ahụ, a na-emeziwanye nguzogide n'ibu. Akụkụ bituminous na-enye aka na-aga n'ihu nke mkpuchi ahụ dị mkpa ma na-ebelata mpaghara nke ebe efu.

Mastic BPM-4

BPM-4 bụ usoro emelitere nke mastic BPM-3. Karịsịa, e nwere ihe ndị na-eme ka modul nke elasticity nke ihe ahụ dịkwuo mma, nke nwere mmetụta dị mma na nkwụsi ike nke mkpuchi.

Na mgbakwunye, BPM-4 rubber-bitumen mastic ji:

• Ọnụnọ mmanụ mmanụ nwere amine, nke na-enye mmetụta mgbochi corrosion ọzọ nke na-adịru ogologo oge.
• Ịbawanye ngbanwe nke elu a na-emeso ya, nke dị mkpa karịsịa maka ụgbọ ala na-arụ ọrụ n'okporo ụzọ ọjọọ.
• Ịba ụba enyi na gburugburu ebe obibi mgbe a na-eji ya eme ihe, ebe ọ bụ na ọ nweghị ihe ndị na-akpasu usoro iku ume.
