Na polymer roba ntụ ntụ nwere mmetụta lubricating n'etiti ihe ndị ahụ, nke mere na ngwa ngwa ngwa nwere ike ịgba ọsọ n'adabereghị. N'otu oge ahụ, ntụ ntụ roba nwere mmetụta na-emepụta ihe na ikuku, na-enye mkpakọ ngwa ngwa ma na-emeziwanye ihe owuwu na ịrụ ọrụ nke ngwa agha.
Ngwa ngwaahịa nke polymer ntụ ntụ na-ekesa
1. Sistemụ mkpuchi ọkụ mgbidi mpụga:
Ngwakọta ejikọta: Gbaa mbọ hụ na ngwa agha ahụ jikọtara mgbidi ahụ na bọọdụ EPS. Melite ike nkekọ.
Ngwa ngwa plastering: iji hụ na ike igwe, mgbape mgbawa na ịdịte aka nke sistemu mkpuchi ọkụ, yana nguzogide mmetụta.
2. Ihe nrapado tile na ihe na-eme ka ọ na-eme ihe:
Adhesive Tile: Na-enye njikọ dị elu na ngwa agha ahụ, na-enye ngwa agha ahụ mgbanwe zuru oke iji mebie ọnụọgụ mgbasawanye ọkụ dị iche iche nke mkpụrụ na taịlị.
Filler: Mee ka ngwa agha ahụ ghara imeri ya ma gbochie ntinye mmiri. N'otu oge ahụ, ọ nwere ezigbo adhesion na nsọtụ nke tile, obere shrinkage na mgbanwe.
3. Nrụgharị tile na plasta osisi putty:
Melite ike nchikota na ike njikọ nke putty na ihe ndị pụrụ iche (dị ka elu tile, mosaics, plywood na ihe ndị ọzọ dị mma), wee hụ na putty nwere ezigbo mgbanwe iji kpata ọnụọgụ mgbasawanye nke mkpụrụ.
Nke anọ, n'ime na mpụga mgbidi putty:
Meziwanye ike njikọ nke putty wee hụ na putty nwere ụfọdụ mgbanwe iji chekwaa mmetụta nke mgbasawanye dị iche iche na nrụgide nrụgide sitere na ọkwa ntọala dị iche iche. Gbaa mbọ hụ na putty nwere ezigbo nguzogide ịka nká, enweghị ike na mgbochi mmiri.
5. Ngwa agha ala na-ebuli onwe ya:
Iji hụ na nkwekọ nke modulu na-agbanwe nke ngwa agha na iguzogide ike na-ehulata na mgbawa. Melite nguzogide iyi, ike nkekọ na njikọta nke ngwa agha.
6. Ngwa ngwa ihu:
Meziwanye ike elu nke mkpụrụ ma hụ na adhesion nke ngwa agha ahụ dị.
Asaa, igwe anaghị egbochi mmiri nke simenti:
Gbaa mbọ hụ na arụ ọrụ mgbochi mmiri nke mkpuchi ngwa agha, ma n'otu oge ahụ nwee ezigbo nrapado na ala ala, meziwanye ike mkpakọ na mgbanwe nke ngwa agha ahụ.
Asato, rụkwaa ngwa agha:
Gbaa mbọ hụ na ọnụọgụ mgbasawanye nke ngwa agha na mkpụrụ osisi dakọtara, wee belata modul na-agbanwe nke ngwa agha ahụ. Jide n'aka na ngwa agha ahụ nwere ihe mgbochi mmiri zuru oke, ume iku ume na nrapado.
9. Ngwa eji akwa akwa:
Melite njide mmiri.
Na-ebelata mfu mmiri ka ọ bụrụ ihe ndị nwere porous.
Meziwanye ịdị mfe nke ịrụ ọrụ ihe owuwu ma melite arụmọrụ ọrụ.
