Kupfuura Silicone Zvekushandisa paChisimbiso Chisingapindi Mvura

Nguva Yekutarisa Kupfuura Silicone Sealant

Silicone isimbi inovhara zvinhu yakavimbika, asi zvinodiwa nemapurojekiti chaiwo zvinowanzoda mhinduro yakasiyana. Kusagadzikana kwemusika munguva pfupi yapfuura ndiko kwakakonzerawo shanduko iyi. Kukanganiswa kukuru kwecheni yekugovera zvinhu muna 2021 kwakaita kuti mitengo yesilicon iwedzere ne300% mukati memwedzi miviri isingasviki, zvichimanikidza nyanzvi dzakawanda kuti dzitsvage dzimwe nzira dzakagadzikana uye dzinoshanda zvakanaka. Zvinhu zvakaita sekugoverwa kwesimba muChina, iyo inogadzira simbi zhinji dzesilicon pasi rose, uye kunonoka kwezvekushandisa pasi rose zvakagadzira dutu rakanaka. Nzvimbo iyi yakaratidza kudiwa kwezvisimbiso zvinogadzirisa matambudziko kupfuura kuwanikwa chete.

Basa Rako Rinoda Kupendwa

Chimwe chezvikonzero zvinowanzo shandiswa kusarudza imwe nzira ndeyekuda kwenzvimbo inopendwa. Zvivharo zvesilicone zvakajairika zvakagadzirwa nesilicone, zvichireva kuti zvinodzinga mvura uye, zvinosuwisa, pendi. Pendi haizonamati zvakanaka kune silicone bead yakarapwa, zvichiita kuti iparare, ibve, uye ipenye zvisina kunaka.

Zano reNyanzvi:Kana paine chisimbiso chisina musono, chine mavara akafanana pamadziro, pamadziro, kana pamadziro, chisimbiso chinopendwa hachigone kutaurwa nezvacho. Ma hybrid polymers nemamwe ma polyurethanes akagadzirwa kuti apendwe zvakanyanya mushure mekugadziriswa.

Unoda Simba Rakanaka Uye Kugara Nguva Yakareba

Kushandiswa kwekuvaka nemaindasitiri kunowanzoda zvinopfuura chipingamupinyi chisingapindi mvura. Zvinoda chisimbiso chinobatsira kuti chibatane zvakanaka. Zvimwe zvakaita sepolyurethane zvinobudirira mune izvi, zvichipa simba rakawanda rekusunga uye kuramba kukweshana zvichienzaniswa nesilicone. Izvi zvinoita kuti zvive zvakanaka munzvimbo dzine vanhu vakawanda, nzvimbo dzinowedzera mafambiro emvura, uye nzvimbo dzinoshandiswa uko kushanda kwemvura kwakanyanya kwakakosha. Kunyange zvazvo polyurethane ichipa simba guru, vamwe vashandisi vanoti hutano hune chekuita nehuwandu hwayo hweisocyanate panguva yekushandiswa, zvichiita kuti kubata kwakakodzera kuve kwakakosha.

Uri Kuvhara Zvinhu Zvakasiyana

Mapurojekiti anowanzo sanganisira kubatanidza marudzi maviri akasiyana ezvinhu, zvakaita semafuremu emahwindo evinyl kumadziro ekongiri kana mapuranga emapuranga kumadziro esimbi. Zvinhu izvi zvinokura uye zvinokotama nematanho akasiyana nekuchinja kwetembiricha. Zvivharo zvakawanda zvepolyurethane nehybrid polymer zvinonamatira zvakanyanya uye zvinokwanisa kufamba zvakanaka. Kuchinjika uku kunovabvumira kuchengetedza chisungo chakasimba, chisingapindi mvura pakati pezvinhu zvakasiyana pasina kutsemuka kana kukweva, zvichiita kuti chisimbiso chigare kwenguva refu uye chakavimbika.

Unoda Kuramba UV kana Chemical Zviri Nani

Zvivharo zvesilicone zvinogara zvichishanda zvakanaka mumamiriro ezvinhu akawanda, asi zvine hurema. Kugara kwenguva refu uchivhenekerwa nezuva zvakananga uye makemikari akaomarara kunogona kuita kuti zviore. Mwaranzi yeUltraviolet (UV) inobva kuzuva inoputsa chimiro chepolymer mune mamwe masilicone. Maitiro aya anotungamira kune yero, choko, uye pakupedzisira kutsemuka, izvo zvinokanganisa chivharo chisingapindi mvura. Kune mapurojekiti anotarisana nezuva kana kusangana nemakemikari nguva dzose, mhinduro yakasimba inodiwa.

Mapolymer ehybrid nema polyurethane sealant zvinopa simba rakawanda munzvimbo idzi dzinonetsa. Zvakagadzirwa kuti zvikwanise kutsungirira zvinokanganisa nharaunda zvinoita kuti zvimwe zvinovhara zvisashande zvakanaka.

·Kuramba UV:Zvivharo zveHybrid (MS Polymer) isarudzo yakanaka kwazvo yekushandisa kunze. Zvine zvinodzivirira UV zvinodzivirira kusviba kweruvara uye kuora kwezuva. Izvi zvinoita kuti zvive zvakanaka pakuvhara mahwindo, magonhi, uye pamadziro akavharirwa nezuva, zvichiita kuti chivharo chirambe chakachinjika uye chisina kusviba kwemakore.

·Kusagona Kurwisa Makemikari:Zvivharo zvepolyurethane zvinogara kwenguva refu zvisingakuvadzi makemikari. Zvinodzivirira kukuvara kunokonzerwa nemafuta, mafuta, zvinonyungudutsa, uye zvinhu zvinochenesa zvine simba. Izvi zvinoita kuti zvive sarudzo inosarudzwa yekuvhara majoini mumakicheni ekutengeserana, mumagaraji emotokari, pasi pefekitori, nedzimwe nzvimbo dzemaindasitiri uko makemikari anowanzo sangana.

·Kusarudza chivharo chine chimiro chakakodzera chekudzivirira inguva refu. Zvinodzivirira kukuvara nguva isati yakwana, zvinoderedza mari yekugadzirisa, uye zvinovimbisa kuti chivakwa chacho chinogara kwenguva refu. Chivharo chinokundikana nguva isati yakwana chinoda kubviswa kunodhura uye kushandiswazve, zvichiita kuti kusarudza zvinhu zvepakutanga kuve kwakakosha kuti chirongwa chibudirire.

Kunzwisisa Zvisimbiso zvePolyurethane (PU)

Zvivharo zvePolyurethane (PU)manamira ane simba, anonamira hunyoro anozivikanwa nekusimba kwawo uye kugona kwawo kubatana kwakasimba. Nyanzvi dzinowanzo asarudza pamabasa akaomarara ekuvaka uye emaindasitiri uko mashandiro emakanika ari epamusoro. Maumbirwo awo akasiyana emakemikari anopa chisimbiso chakasimba asi chinochinjika chinotsungirira kushushikana kwakakura.

Mabhenefiti Akakosha ePolyurethane

Zvivharo zvepolyurethane zvinopa musanganiswa wakasiyana wesimba uye kutwasuka. Cheni yavo yepolymer ine zvikamu zvakaoma uye zvakapfava. Dhizaini iyi inogadzira chigadzirwa chinogara kwenguva refu uye chinochinjika, zvichiita kuti chive sarudzo yepamusoro yemabasa akaoma ekuvhara. Zvakanakira zvikuru zvinosanganisira:

·Kunamatira Kunoshamisa:Zvivharo zvePU zvinonamatira zvakasimba pazvinhu zvakawanda zvekuvaka. Zvinonyanya kubatana zvakanaka nemidziyo ine maburi yakaita sekongiri, masonry, uye huni.

·Kusimba Kwakanyanya:Izvi zvinovhara majoini zvinokwanisa kufamba kwakakosha kubva pakuchinja kwekushisa, mhepo, kana kudedera. Kuchinjika uku kunodzivirira chivharo kuti chisatsemuke kana kupera simba nekufamba kwenguva.

Musanganiswa uyu unovimbisa chisimbiso chinogara kwenguva refu, chisingapindi mvura kunyangwe munzvimbo dzinoshanduka.

Zvipingamupinyi uye Kubata

Kunyange zvazvo zvine simba, ma polyurethane sealant ane zvinodiwa chaizvo pakubata. Ane isocyanates, ayo anogona kukonzera kushatirwa kwesealant isati yapora zvizere. Midziyo yakakodzera yekudzivirira munhu (PPE), kusanganisira magirovhosi nemagirazi ekuchengetedza, zvakakosha. Kufefetera kwakanaka munzvimbo yebasa kwakakoshawo panguva yekuisa. Pamusoro pezvo, ma PU sealants akajairwa anogona kuve panjodzi yekuora kweUV nekufamba kwenguva, izvo zvinogona kukonzera kudonha kwechoko kana kuchinja ruvara kunze kwekunge akapendwa kana kugadzirwa zvakananga neUV inhibitors.
