Mineral wool mahwendefa: maitiro uye GOST

Kuzivikanwa kukuru kwemaminerari emvura kunokonzerwa, pamusoro pezvose, kumadhura avo akaderera uye maitiro akanaka ekushanda. Izvi zvinyorwa zvinogona kushandiswa kugadzirisa zvakasiyana-siyana zvezvivakwa - masvingo, denga uye pasi redzimba dzevanhu, mapaipi, kupisa magetsi, nezvimwewo.

Zvinhu zvakasikwa

Sezvakakoswa pakugadzirwa kwezvinhu zvakadai semamineral wool plates, kusviba kwematombo emakomo, girazi uye kupiswa kwevira yevira rinoshandiswa. Ichi chinopisa chinokonzerwa nemasikisi chinodyiwa mune imwe nzvimbo inokosha inoshandiswa (iyo zvichibva pakutsvaga kwemhepo) inoshandurwa kuva muspuru. Uyezve, vasungwa vanoiswa mazviri. Kazhinji, phenol-formaldehyde resin inowanikwa mumabasa avo . Uyezve, iyo yakanakira "machira emakoloni" inouya pasi pevanyori vanoita kunyange hutete. Pachigumo chekupedzisira, zvinhu zvakagadzirwa mu slabs zvehuwandu hwakakosha.

Mafudzi emakumbo emakamuri anogona kuwanikwa ose muhutano hwakashata, uye achienzanisa. Shanduro yekupedzisira yezvinyorwa inonzi laminar, ine simba rakakura uye yehutano hwehutano conductivity, inosiyaniswa nesimba rinowedzera. Dzimwe nguva mahwendefa emvere dzemaminera anosungirirwa kune rumwe rutivi nemafuta akareba eumuminium.

Degree of fire resistance

Iyo inonyanya kukosha yehutu hwemaminerari pakuenzanisa nemamwe emishonga inokonzera kusakanganiswa kwayo. Inobvumirwa kushandisa mashoko aya kuitira kupisa kwepamusoro, iyo inotonhorera iyo inosvika kusvika kune +400 degrees Celsius. Ndicho chikonzero chidimbu chemashizha ehuruti ndiyo yakanyatsodzivirira yeaiti nemafuta emhando dzakasiyana. I- basalt fiber inotanga kusungunuka chete mushure meawa maviri iri kutaridzika kumusana wezvidigiri 1000. Ichi chiratidzo chinoshamisa. Kana zviri zvekushisa kwemhepo yakadzika, uye pasina kuzvikuvadza iwe pachako iyi inogona kumira mahara 750. Iko kusvibiswa kweboka remaminerari ndiro ndiro KM0. Mumiriri yakasiyana-siyana - KM1.

Degree yekupisa conductivity

Chinangwa chikuru chehuta hwemaminerari ndekudzivirira dzimba, zvigadzirwa uye kutaurirana kubva kunotonhora. Iko kunobvumirwa kunotisa hutsika hwehupfumi hunosimbiswa neGOST 4640-2011. Iyi nhamba inowirirana zvichienderana nekupisa kwemazuva uye inogona kubva kubva ku 0.038 W / (mK) pane kutonhora kwe + 10 degrees kusvika ku0010 W / (mK) pa +300 degrees. Nokudaro, kukwanisa kuchengetedza kupisa, chinhu ichi chakakwirira kune vazhinji vanozvidzivirira mazuva ano. Uyu unhu hunokonzerwa nehupfumi hwehupfumi nehuwandu hwakawanda hwemhepo dzepamusoro.

Kuwedzera

Iyi nhamba yezvinhu zvakadai, semamineral wool kupisa-kuvhara mahwendefa, inogona kuchinja mumiganhu yakakura (30-220 kg / m ³ ). Iyo yakakwirira kuwanda kweplate, iyo huru inoparadzirwa inogona kumira. Maererano nenyaya ino, mvere dzemaminerari dzinogona kuiswa muzvikamu zvitatu:

• Low density (30-50 kg / m ³ ). Uturu hwekotoni yakadaro hunoshandiswa kunyanya kunopisa nzvimbo dzakakwirira.
• Ivhareji yakawanda (60-75 kg / m ³ ). Izvi zvakasiyana-siyana zvinowanzoshandiswa kusiyanisa zvakasiyana-siyana zvezvivakwa zvekugadzira.
• High density (80-175 kg / m ³ ). Mabhandi akadaro anogona kushandiswa kuisa masvingo mukati kana kunze kwezvivako.
• Yakakura kwazvo (180-200 kg / m ³ ). Izvi zvakasiyana-siyana zvinowanzoshandiswa kushandiswa kwematenga.

Uwandu hwezvinhu zvakadai semaminera ehuruti mahwendefa chiratidzo chinongogonesa kukwanisa kumira mitoro. Dhigirii yemhepo inotungisa inenge isingabatsiri.

Watertightness

Kunyanya kushorwa kumhepo inopinda mune imwe yezvipingamupinyi zvishomanana izvo mineral wool plates zvine. GOST yekuedza kuenderera kwemashoko aya nemitemo maererano nekudzivirira kwemvura inoda miedzo yakakosha. Panguva imwe chete, sampuli dzinotorwa kubva munzvimbo dzakasiyana dzeplate (20-30 gramu). Zvadaro zvinowanikwa mumukombe wekanda uye calcined pakushambidzika kwemadigiri 600 kuti ibvise kusvibiswa kwezvinhu. Zvadaro huwandu hunoita kuti uve mupfu, hwakakanyiwa nemadonho mashomanana eodl doro, uye zvishoma nezvishoma hydrochloric acid inowedzerwa. Uyezve, magetsi emakiromita anonzi pH anoderedzwa mumudziyo. Mushure memaminitsi ane gumi anokurudzira, pH yemuriyo inoenzaniswa. Kupikisa kwemvura kwezvinhu zvakagadzirirwa kubva pachireji pH kukosha.

Mineral slaol slabs (GOST inotsanangura kusadzivirira kwemvura muhuwandu husingasviki kune 4-7 pH) inonwisa mvura zvakanaka, kurasika zvimwe zvekudzivirira kwemafuta. Zvisinei, chiyero chemuviri wavo wehutema nehukuru haufaniri kudarika 1%. Kuti kuwedzerwa kusagadzikana kwezvinhu zvakanyanyisa kusvika kune hunyoro, zvinogadziriswa ne-hydrophobizator chaiyo.

Mvura inopisa simba

Kune zvakakosha zvezvinhu zvakadai semaminera emapuranga emapuranga, imwe inogona kusanganisira, pakati pezvimwe zvinhu, kukwanisa kudarika mamolekemu emvura kuburikidza nega. Iko yeji yehuputi yekuputika kwehuni hwemaminerari ndeye 480 * 10-6 g / (m * h * Pa). Inofananidzwa kune dzimwe nyanzvi dzemazuva ano, iyi ndiyo yakakwirira kwazvo.

Fiber nzvimbo

Uturu hwemaminara ane chaotic urongwa hwemagetsi ane simba rinokwana 120-160 kg / m ³ uye simba rakasimba re10 kPa. Izvi zvakasiyana-siyana zvinowanzogadzirwa mu slabs dzine urefu hwe 120-160 masentimita uye upamhi hwa 50-60 masikati. Basalt mvere dzemapuranga nemagadzirirwo emagetsi (lamellar) anozivikanwa nehukuru hunokwana 80-120 kg / m ³ uye simba rakasimba re 80 kPa. Kuyera kwemahwendefa eizvi zvakasiyana-siyana ndea 120 x 20 cm. Kubwinya kwemaminerari emakumbo emabhandi anosiyana pakati pe30-100 mm.

Mavara mazhinji anozivikanwa

Kazhinji kazhinji muRussia, machira emumota emuchiratidzo "Technonikol" anoshandiswa pakutsanura kwezvinhu zvezvivakwa zvezvivako. Uyu mugadziri anogadzira zvinhu zvakanakisisa zvepamusoro izvo zvinosangana neGOST maitiro ose. Pakati pezvimwe zvinhu, kushandiswa kwayo kusina mubvunzo kunodhura.

Izvo zvisingazivikanwi zvakanyanya ndeye Rockwool mineral wool slabs. Zvigadzirwa zvemugadziri uyu zvinogona kushandiswa kugadzirisa zvachose zvigadziriswa zvemuumbi uye simba rekushandisa. Basalt wool yemuchina uyu inobudiswa mumhando dzakasiyana-siyana uye zvakashata.

Nzvimbo yekushandiswa

Mipuranga yemakushe emakamuri okuisa zvinyorwa anoshandiswa:

• Zvepabonde;
• Mazhenesheni anoputika;
• Zvidhori zvekuisa;
• Roof;
• Masvingo kubva mukati uye zvikamu;
• Kubatanidzwa;
• Pipelines;
• Ovens uye chimneys;
• Boilers;
• Matambo ekugadzira, nezvimwewo.

Kuchengetedza kwemuchina wemucheka kunoshanda zvikuru uye kwakavimbika. Kubatanidzwa kwekunaka kwemaitiro ekugadzirisa nemari yakaderera kunoita kuti zvive zvakakurumbira kune vose vanogadzira uye makambani makuru emabhizimisi.
