Umbuzo 4.Kutheni kuvela amabala okanye imikhondo esipilini emva kokusebenzisa i-silicone sealant ngasemva?ixesha elithile?

Impendulo:

Ngokwesiqhelo kukho iintlobo ezintathu zeengubo ezifakwa ngasemva kwezipili ezithengiswayo: i-mercury, isilivere ecocekileyo, kunye ne-copper.

Ngokwesiqhelo, emva kokusebenzisa i-silicone sealant ukufaka izibuko kangangexesha elithile, umphezulu wesibuko unokuba namabala. Oku kudla ngokubangelwa kukusebenzisa i-acetic silicone sealant, ephendula kwizinto ezikhankanyiweyo apha ngasentla kwaye ibangele amabala kumphezulu wesibuko. Ke ngoko, sigxininisa ukusetyenziswa kwe-neutral sealant, eyahlulwe yaba ziintlobo ezimbini: i-alkoxy kunye ne-oxime.

Ukuba isibuko esinobhedu sifakwe nge-oxime neutral sealant, i-oxime iya kuyidla kancinci into yobhedu. Emva kwexesha lokwakha, kuya kubakho amabala okugqwala ngasemva kwesibuko apho kufakwa khona i-sealant. Nangona kunjalo, ukuba kusetyenziswa i-alkoxy neutral sealant, le nto ayiyi kwenzeka.

Zonke ezi zinto zingentla zibangelwa kukukhethwa kwezinto ezingafanelekanga okubangelwa kukwahluka kwezinto ezisetyenziswa phantsi komhlaba. Ke ngoko, kuyacetyiswa ukuba abasebenzisi benze uvavanyo lokuhambelana ngaphambi kokusebenzisa i-sealant ukuze babone ukuba i-sealant iyahambelana na nezinto.

Umbuzo 5.Kutheni ezinye izitywini ze-silicone zibonakala njengee-granules ezinobukhulu beekristale zetyuwa xa zisetyenziswa, kwaye kutheni ezinye zezi granules zinyibilika zodwa emva kokuba zinyibilikile?

Impendulo:

Le yingxaki ngefomula yezinto ezisetyenzisiweyo ekukhetheni i-silicone sealant. Ezinye i-silicone sealant ziqulathe ii-cross-linking agents ezinokunyibilika kumaqondo obushushu aphantsi, nto leyo ebangela ukuba i-cross-linking agent iqine ngaphakathi kwibhotile ye-adhesive. Ngenxa yoko, xa i-adhesive ikhutshwa, ii-granules ezifana netyuwa ezinobukhulu obahlukeneyo zinokubonakala, kodwa ziya kunyibilika kancinci ngokuhamba kwexesha, nto leyo ebangela ukuba ii-granules zinyamalale ngokuzenzekelayo ngexesha lokunyibilika. Le meko ayinampembelelo ingako kumgangatho we-silicone sealant. Isizathu esiphambili sale meko yimpembelelo ebalulekileyo yamaqondo obushushu aphantsi.

Umbuzo 8.Kutheni ezinye izitywini zesilicone ezingathathi cala ezisetyenziswa kwindawo ekudibana kuyo iifreyimu zekhonkrithi nezentsimbi zenza amaqamza amaninzi emva kokuphola ehlotyeni, ngelixa ezinye zingenzeki? Ngaba yingxaki yomgangatho? Kutheni le nto ingazange yenzeke ngaphambili?

Impendulo:

Iintlobo ezininzi ze-silicone sealant engathathi cala ziye zadibana neziganeko ezifanayo, kodwa ngokwenene ayingombandela womgangatho. I-Neutral sealants ziza ngeentlobo ezimbini: i-alkoxy kunye ne-oxime. Kwaye i-alkoxy sealants ikhupha igesi (i-methanol) ngexesha lokuqina (i-methanol iqala ukutsha kwi-50℃), ingakumbi xa ivezwe elangeni ngqo okanye kumaqondo obushushu aphezulu.

Ukongeza, izakhelo zefestile zekhonkrithi nezesinyithi azingeni kakhulu emoyeni, kwaye ehlotyeni, xa amaqondo obushushu aphezulu kunye nokufuma, i-sealant iphiliswa ngokukhawuleza. Igesi ekhutshwa kwi-sealant inokuphuma kuphela kumaleko we-sealant ophiliswe kancinci, nto leyo ebangela ukuba kuvele amaqamza obungakanani obahlukeneyo kwi-sealant ephiliswe. Nangona kunjalo, i-oxime neutral sealant ayikhuphi igesi ngexesha lenkqubo yokuyicoca, ngoko ke ayivelisi amaqamza.

Kodwa ingxaki ye-oxime neutral silicone sealant kukuba ukuba ubuchwepheshe kunye nefomyula aziphathwanga kakuhle, zinokuncipha kwaye ziqhekeke ngexesha lenkqubo yokunyanga kwimozulu ebandayo.

Kwixesha elidlulileyo, izinto ezifanayo bezingenzeki kuba izinto zokutywina ze-silicone zazingasetyenziswa rhoqo kwiindawo ezinjalo ziiyunithi zokwakha, kwaye izinto zokutywina ezingangeni manzi ze-acrylic zazisetyenziswa endaweni yoko. Ke ngoko, into yokuqhumisa kwi-silicone neutral sealant yayingaqhelekanga kakhulu. Kwiminyaka yakutshanje, ukusetyenziswa kwezinto zokutywina ze-silicone kuye kwanda kancinci kancinci, nto leyo ephucula kakhulu umgangatho wobunjineli, kodwa ngenxa yokungaqondi kakuhle iimpawu zezinto, ukukhethwa kwezinto ezingafanelekanga kukhokelele kwinto yokuqhumisa i-sealant.
