Chophimba chazenera pa mawindo apulasitiki

Chisindikizo chawindo cha pulasitiki chimachita ntchito yotsekemera, chimateteza mkati mwa malo kuchokera kunja kwa phokoso, kuzizira, mphepo, ndi chinyezi. Mukhoza kuchigwiritsa ntchito m'mawindo a nyumba za cholinga chilichonse. Posachedwa, anthu okhala m'nyumba zamakono ndi zipinda zamakono akuyambanso kuyika mawindo apulasitiki, omwe amasiyana mofanana ndi ogwira ntchito kuchokera ku matabwa awo. Ndi chithandizo chawo, mutha kuchepetsa mtengo wa zotentha zothandizira. Koma m'kupita kwanthawi, chilichonse, ngakhale chinthu chapamwamba kwambiri chingathe kulephera, mawindo apulasitiki sizinasinthe. Kusindikiza chingamu ndi zinthu zina zamakono zamakono zimasowa kukonza.

Kufotokozera

Chisindikizo chawindo chimatchinjiriza zinthu zakunja kulowa mu chipinda. Ndicho, mukhoza kuteteza zipangizozo kuchokera ku chinyezi, zomwe zingathe kuwononga. Zisindikizo zimakhala ndi mphamvu zamphamvu, zomwe nthawi zina zimafaniziridwa ndi zikhalidwe zomwe zimapezeka mu rabala yowonongeka. Kugwiritsa ntchito zisindikizo zoterezi kungatheke pa kutentha kwakukulu, komwe kumakhala kosiyana -40 mpaka +55 ° C. Zinthu izi zimagonjetsedwa ndi kusintha, ndi zachilengedwe, ndipo malo awo ogwiritsira ntchito ndi ochuluka kwambiri. Ngati tikulankhula za chilengedwe, chisindikizo chawindo sichikhala ndi zinthu zomwe zingakhale zoopsa. Kuyendera sitolo, mungasankhe mtundu wa chisindikizo, chomwe chidzafanane ndi mthunzi wazenera.

Zolemba zamakono

Zisindikizo zowonjezera zimatha zaka 30, ndipo kutentha kwake kumatha kusintha malinga ndi makina opangira. Zomwe zimayambira pazimenezi sizimveka bwino kwa ozoni ndi ma ultraviolet. Zomangamanga zosiyana siyana za zisindikizo zingasinthidwe, kotero muyenera kusamala kwambiri nkhaniyi.

Sankhani ndi zinthu: Zisindikizo za mphira ndi silicone

Katswiri wamakono opanga mphira wa mphira umaphatikizapo kutulutsa mphira pogwiritsa ntchito sulfa ndi ultraviolet. Chigawo chachikulu ndi carbon black, zinthu izi zingagwiritsidwe ntchito kwa zaka 30. Chizindikiro ichi chachisindikizo chimayika chisindikizo cha ziwalo zonse zomwe zilipo.

Silicone ili wokonzeka kukhalapo kwa zaka 10. Pogwiritsa ntchito zinthu zimenezi, magwiritsidwe ntchito ochezeka a zachilengedwe omwe awonjezeka kusagwirizana ndi kusintha kwa kutentha. Zogulitsa sizimatayika panthawi ya opaleshoni, ngakhale kutentha kumasiyanasiyana -40 mpaka +150 ° C. Zinthuzo zimagonjetsedwa ndi dzuwa, mpweya ndi ozoni.

EPDM ndi TPE Zisindikizo

Chisindikizo chawindo cha mawindo apulasitiki chikhoza kupangidwa kuchokera ku ethylene propylene. Moyo wautumiki pa nkhaniyi umatha zaka makumi awiri, zomwe zimagonjetsedwa ndi zinthu zomwe zili m'mlengalenga ndipo sizimasokoneza, zomwe zimalola kuti zigwiritsidwe ntchito moyenera pa cholinga chake. Pamene nkhaniyi ikuchokera ku thermoplastic elastomers, dzina limveka ngati TPE, pomwe zinthuzo zimawoneka ngati mphira, pogwiritsa ntchito ma polima opangidwa.

Zida za PVC sealant

Chisindikizo chazenera, maonekedwe omwe mungathe kudzipatula ndi kuteteza, angapangidwe ndi PVC, yomwe ili ndi ubwino wambiri komanso zovuta zina. Zingagwiritsidwe ntchito pokhapokha m'nyumba zowonjezera, koma nthawi yogwira ntchitoyi ndi zaka zitatu zokha. Mapulogalamu opanga zipangizo zamakono ndi osavuta kumvetsa zofanana ndi zomwe zikufanana, zomwe zimakhudzadi mtengo, womwe, mwatsoka, sunganene za khalidwe.

Chofunika chotsitsa sealant

Rabala pawindo amafunika kusintha m'malo mwake, ngati muwona kuti pulojekitiyi imalowa muzipinda, kukondwera pamwamba pa mawindo, ndipo mawindo omwewo anayamba kufungatira. Choncho, mkati mwa mkati, chisanu chingapangidwe, chomwe chimapangitsa kuvala kwathunthu kapena kwapadera kwa mphira woyika chisindikizo. Mapangidwe a condensate angakhale chifukwa cha kutseka kwa tsamba, zomwe zimapangitsa kutentha pakati pa magalasi kuchepa, komwe kumapangitsa kuti pakhale chinyezi.

Kusintha chidindocho

Ngati silicone sealant yalephera, yatayika katundu wake ndipo sichiteteza mbiriyo, ndiye iyenera kuti idzasinthidwe. Kuti muchite izi, muyenera kugwiritsa ntchito zipangizo ndi zipangizo zina, pakati pawo:

• Mikanda yowopsya;
• Chothandizira;
• Kusindikiza zakuthupi.

Pakafunika kuchotsa chidindo chakale, ndikofunika kuyeretsa pores of disamination, chifukwa izi mungagwiritse ntchito bulashi. Mitengoyi imatha kupukutidwa ndi nsanza yonyowa pokonza kenako imakhala bwino. Makona amathandizidwa ndi guluu, ntchito ikugwiritsidwanso ntchito komanso malo omwe kukhazikitsidwa kwa zinthu zatsopano. Chingwe chiyenera kukhala chofunika kwambiri, ndikofunika kudula mopitirira muyeso ndi lumo, ndipo ziwalozo zikhale pamodzi, kugwiritsa ntchito guluu.

Malangizo a katswiri

Chisindikizo cha mafelemu a mawindo sichiyenera kuimitsidwa panthawi yowonjezera. Pofuna kupewa malo osindikizira, mungagwiritse ntchito njira yosindikiza kusinthika, chifukwa chaichi, fungulo laikidwa mu dzenje lapadera ndipo linasinthidwa kufikira mutapeza zotsatira. Ngati njirayi isalole kuti izi zitheke, ndiye kuti pa tsamba loyamba tsamba lawindo lichotsedwe, ndibwino kuti tichite izi kuyambira kumtunda wapamwamba. Kenaka chisindikizo chakale chimachotsedwa, ndipo kenaka chatsopano chimayikidwa ku grooves, koma m'pofunika kuchita pang'onopang'ono.

Mukamayika zenera zowonjezera mphira, simukusowa kuchotsa khunyu wakale. Ndibwino kugwiritsa ntchito chigawo chatsopano. Yambani ndi ndondomekoyi musakhale, chifukwa gululi likhoza kupaka. Ndikofunika kuyembekezera kuyanika kwathunthu kwa chisakanizocho, pokhapokha atakonzedwa kukhazikitsa tsamba lawindo pa malo. Ngati zinaoneka kuti rabala wakale siinathe kuwonongeka ndipo ingagwiritsidwebe ntchito, chidindocho chimalimbikitsidwa kuti chibwezeretsedwe, chifukwa chaichi chimakanizidwa ndi mafuta a aerosol.

Zowonjezera zosankha posankha sealant

Ngati simukudziwa kuti ndi chisindikizo chiti chomwe mungasankhe, ndiye kuti muyenera kumvetsera zochitika za aliyense wa iwo. Mwachitsanzo, polima amapangidwa kuchokera ku polyvinyl chloride, koma ali ndi ubwino wodalirika chifukwa cha nyengo yoipa. M'chilimwe, chidindo chotere chimachepetsa, ndipo chimakhala cholimba m'nyengo yozizira, pakati pazinthu zina, chimawonekera ku dzuwa. Koma zisindikizo za mphira ndi raba ndizo zodalirika komanso zogwiritsidwa ntchito kwambiri. Ali ndi makhalidwe omwe amakumana nawo kutentha kwambiri. Ultra-violet pa zisindikizo zotere sizimakhudzidwa, iwo ali ndi mphamvu yokhazikika. Wowonjezeramo makina othandizira angapangidwe ndi polyethylene ndi mphukira ya mphutsi. Zinthu izi sizodziwika chifukwa cha khalidwe losauka komanso mitundu yosiyanasiyana. Silicone yamtengo wapatali kwambiri, choncho sichikondwera kwambiri. Zinthuzi sizingatheke, zimakhala zotsika kwambiri ndipo zimakhala zochepa poyerekeza ndi mphira wa mphira. Mphepo yamkuntho ndi chitetezo cha phokoso chimakhala ndi pulogalamu ya EPDM.

Kutsiliza

Moyo wautumiki wa mphira wa chisindikizo udzadalira osati zowononga chabe, koma ndikukonzanso bwino. Kuwonjezera moyo wawindo ili, ayenera kukhala woyera. Kuti tichite zimenezi, ngati n'kofunikira, pamwamba pa sealant imatsukidwa ndi dothi ndi fumbi, yokhala ndi gel osakaniza. Njira zoterezi ziyenera kuchitika kangapo pachaka, pokhapokha pazifukwa zoterezo m'malo mwa nsalu zamabambo akhoza kuchitidwa mobwerezabwereza.
