Ubutandukane hagati y'Igikoresho co Gukingira Silikoni n'Igikoresho co Gukingira Silikoni

I. Ubutandukane mu bihimba n'uburyo bwo kuvura
1. Igipfukisho ca silikoni kitagira aho kigarukira:

- Igikoresho nyamukuru: ivyuma vy’amazi-ivy’amazi vy’amazi. Ivura biciye mu gukuraho inzoga mu gufata ubukonje buva mu kirere, igahingura elastomere ishobora guhinduka iyo ikize.

- Ikira buhoro (tack-igihe c'ubusa nk'iminota 30-60, gukira gushitse bifata amasaha 24-72), bikaba bituma ibereye ibikorwa bisaba gusubira gushiramwo.

- Nta aside irimwo kandi nti-ishobora gutera ivyatsi nk'ivyuma n'ibirahuri. pH yayo iri hafi y’ubudasa (6,5-7,5).

2. Igikoresho co kwifatanya n'imiterere ya silikoni:

- Yongerako silanes canke amapulasitike yahinduwe kugira ngo akore umurongo w’ubufatanye urengeye canke ungana na 0.4 MPa iyo ukize. Hari ibintu vyemewe bishingiye ku rugero rwa ASTM C1184.

- Gukira vuba (tack-igihe c’ubusa 20-iminota 20{5}}40) n’inkomezi nyinshi z’ugufatanya (inkomezi z’ugukomera Birengeye canke bingana na 0.7 MPa, raba GB 16776-2005), bikaba bituma ibereye gukoreshwa mu bibanza vyikorera umuzigo.

II. Kugereranya ibikorwa n'ugukoresha
1. Ivyiza vy'ubuhinga:

- Ivyuma bikingira silikoni bitagira aho bihuriye bifise ubushobozi bwo gukomera 0.5-1.0 MPa n’uburebure bwa 200%-300%, bikaba bituma bishobora gukingira amajosi akora (nk’ibihengeri biri hagati y’inzugi n’amadirisho).

- Ivyuma bifatanya n’ibintu vy’imibumbe vy’i silikoni biri hagati muri rusangi bifise inkomezi zo gukomera zirenga 1,0 MPa, hariho n’inkomezi zimwe zimwe zikomeye -zishika kuri 1,5 MPa (nka Baiyun SS622). Bikoreshwa cane cane ku bikorwa vyo gufatanya ibintu nk’inkuta z’ibirahuri n’ibuye ryumye-rimanikwa.

2. Uguhangana n’Ikirere n’Ubushuhe:

- Vyompi birashobora guhangana n’imishwarara ya UV-, ariko ivyuma bifatanya n’ibindi bikoresho bifise ubushuhe bw’igihe kirekire- (-40 degrees gushika 150 degrees , ugereranyije na -50 degrees gushika 120 degrees ku bikoresho bifatanya n’ibindi bikoresho bitagira aho bihuriye).

Ivyuma bifatanya silikoni bitagira aho bihuriye vyibanda cane ku gukingira amazi no gukingira ibikoko (bihuye n’ingingo ya GB/T 14683-2017), mu gihe ivyuma bifatanya vy’imibumbe bitegerezwa guca mu bigeragezo vy’imitingito (nk’ivyo bita JIS A5758).

3. Ibikorwa bisanzwe:

- Ivyuma bifatanya silikoni bitagira aho bihuriye: Gukingira amazi mu bwogero no gukingira, gutera amabuye, no gukingira amatiyo.

- Ivyuma vy’imibumbe vy’i silikoni: Inkuta z’ibirahuri vy’inyubako ziteye hejuru-, gufatanya ivyumba vy’izuba, n’ugukomeza umugozi w’isanzure.

III. Ukwirinda gukoresha
1. Imbere yo gukoresha ivyuma bifatanya silikoni bitagira aho bigarukira, ahantu hose hategerezwa gusukurwa kugira ngo hatagira amavuta yanduye yoshobora gutuma ivyuma bifatanya. Ivyuma bifatanya ibintu bisaba ko umuntu akoresha ikintu cyumye be n’ugukoresha ikintu co gutera imbere (nk’akarorero, aluminium isaba gukoreshwa mu buryo budasanzwe).

2. Ivyuma bifatanya ibintu bitegerezwa gusuzumwa ko bihuye (bishingiye kuri ASTM C1087) kugira ngo ntibikoreshe imiti n’ibikoresho bikorana.

Ivyo bigereranywa biri hejuru vyerekana ko naho vyose ari ivyuma bifatanya n’ibindi bihimba vy’umubiri, intumbero zavyo zo guhingura n’ibimenyetso vy’ibikorwa vyavyo bitandukanye cane. Abakoresha bakwiye guhitamwo imwe bivanye n’ivyo bakeneye vyihariye.
