Silikoni sealant lakwaniritsa kutchuka mkulu chifukwa lonse kutentha osiyanasiyana kuchokera -50 kuti +250 ^° C chiwerengero A mbali kwambiri anapatsa iye kufalitsa m'minda osiyanasiyana monga zomangamanga magetsi, mankhwala, chakudya ndi nsalu mafakitale, komanso chuma cha dziko ndi zida mafakitale.

Kufotokoza mwa chidule za ubwino ndi

Silikoni sealant mankhwala zochitika ngati zosasangalatsa monga: .. Cold, street phokoso, mvula, etc. Komanso mankhwala kuteteza hardware ku condensate ali linkasokoneza.

Silikoni sealant monyadira zotsatirazi ubwino izi:

• mkulu mphamvu;
• kukhazikika mu yotakata kutentha osiyanasiyana;
• kukana kuti mitundu yosiyanasiyana ya deformations;
• linafalitsidwa kwambiri kuchuluka;
• ukhondo zachilengedwe;
• moyo wautali popanda kusokoneza makhalidwe koyamba zodzitetezera;
• osiyanasiyana yaikulu mitundu.

Kufunika mafuta zisindikizo mphira

Mafuta silikoni mankhwala ena omatira chofunika pofuna kupewa akulimbana, yozizira koopsa ndi msanga kukalamba mankhwala. komanso zimathandiza kuti kwambiri kusintha zizindikiro monga zikayamba, kutchinjiriza phokoso ndi kutchinjiriza matenthedwe.

Pakati pa lubricants otchuka ndi:

• WD 40 - aerosol, amene makamaka amachotsa dzimbiri aliyense padziko zitsulo. Komanso, wothandizila ali ndi mphamvu mkulu ozama, ndipamene filimu zoteteza kuti amapereka mkulu chinyezi kufumbwa katundu, komanso prolongs moyo wa chisindikizo mphira.
• Mastic "zitetezeni ndi kukongoletsa utoto." Silikoni mphira ankachitira ndi mankhwala, ndiye kwambiri yaitali, kugonjetsedwa ndi mpweya ndi ngwadidi kwa nthawi yaitali.
• Glycerin. Ndi viscous, madzi colorless, wokoma kukoma ndi mwamtheradi si amaonekera kwa kununkhiza. Ubwino waukulu monga otsika yozizira koopsa mfundo ndi chiwerengero cha katundu kwambiri hygroscopic.

zakuthupi A oyenera kupanga chisindikizo

chisindikizo akhale chuma chilichonse kusintha:

• silikoni;
• PVC;
• TPE;
• mphira.

Aliyense zipangizo pamwamba ayenera kukhala:

• kugonjetsedwa kusiyana kutentha;
• cholimba;
• hardwearing;
• chinyezi kugonjetsedwa.

Silikoni sealant ndi kutumikira kwa nthawi yaitali kwambiri za nthawi, koma pamene ogwiritsa kapangidwe ayenera kukhala zotheka m'malo.

Chisindikizo cha akusamba

Silikoni mphira chisindikizo chotchuka kwambiri pamene inu kwabasi yamvumbi chifukwa kusiyana ndi kusinthasintha mkulu ndipo ngakhale ndi silikoni, galasi chikukonzekera.

mankhwala angagwiritsidwe ntchito kusindikiza ndi mpanda shawa padziko wozungulira, kuphatikizapo kugwirizana mkati. Mkulu kusinthasintha amatilola kumutcha iye osati monga kusindikiza chingamu.

Malinga akafuna mphira conjugation silikoni kwa akusamba kungakhale:

• A woboola pakati. zisindikizo abwino danga pakati pa galasi ndi pakhoma, komanso galasi ndi galasi.
• T woboola pakati. Inali makamaka pa chitseko pansi.
• W woboola pakati.
• U-zooneka.

Mitundu ya zisindikizo zenera

Posankha chisindikizo kwa zenera pulasitiki, muyenera kulipira chisamaliro osati mtundu ndi Mlengi, komanso makhalidwe a kugwiritsidwa ntchito kupanga ake.

Mitundu ya zipangizo:

1. TPE - zotanuka thermoplastic, amene zayekha mosiyana kusinthidwa pulasitiki. Ena anapanga akuluakulu Kugwa m'manja a ogula kuyambira TPE chisindikizo, monga ntchito pafupifupi makina msonkhano mzere wa mbiri. Chifukwa utali wozungulira ka kupindika mosavuta akhoza welded, ndi gawo ake mtanda akhoza kutenga mawonekedwe aliwonse. Yabwino ofanana chisindikizo makamaka kwa Mlengi, ndi wosuta alandira: kulolerana osauka gradients lakuthwa kutentha, brittleness ozizira ndi ductility mu kutentha, komanso otsika kukaniza ndi zotsatira za chikhalidwe makina ndi cheza ultraviolet. Koma m'malo mwake sadzachititsa mavuto alionse - kufunika yekha mpeni khitchini.
2. EPDM - ethylene propylene mphira chimene chingathe kupirira kutentha iliyonse yapadera, makina amadza, UV ndi mpweya.
3. Silikoni mphira - zofewa kwambiri ndi ulusi ofewa, makhalidwe abwino amene ali zayamba kuposa chimake m'mbuyomu. Kuipa kwambiri, ndi - mtengo.

Nsonga posankha zisindikizo zenera

Silikoni sealant kwa galasi - ichi ndi njira yabwino, popeza si mantha detergents aliyense caustic kapena utoto kapena varnish.

Cholinga cha mankhwala amenewa ndi kutseka mipata chifukwa pakati pa mafelemu ndi malamba. Kupezeka kwa zinthu apamwamba TACHIMATA amasunga chipinda kwambiri chifukwa cha kutentha, nthawi zonse amayesetsa kuti athyole mwa kutsegula kwa.

Old mazenera zinalili mu Soviet Union, amalimata mwa okha zomatira chidindo (Swedish njira). Izi Mzere, kutentha zizimva, umene ndi tepi yomata kuti winded mu mphete angapezeke mu sitolo aliyense hardware.

Modern kudziona zomatira sealant zochokera silikoni ali mawonekedwe zotsatirazi: wapawiri nyemba pamwamba chimake, kumene awiri n'kupanga yopapatiza ntchito flick wa polumikizira.

Ngati kutentha amafuna malo amene ali chibadidwe mu kutentha ndi mkulu chinyezi msinkhu, m'pofunika kupereka mmalo kutenthetsa zosagwira silikoni sealant, monga mutu pofuna kuonetsetsa wangwiro clamping malamba a mawindo (ndi kusamba, anthunzi otulutsirako thukuta kapena bafa).
