Mhedziso yeBasalt Fiber-Yakasimbiswa Plaster Mortar

1. Hunhu Hunokosha hweBasalt Fiber

Basalt fiberinonyanya kuumbwa nesilicon oxide, aluminium oxide, uye iron oxide, ine huwandu hwakanyanya hwesilicon oxide uye aluminium oxide, ichipa mabhenefiti akakosha mukudzivirira kupisa uye. Chemical corrosion resistance. Kana ichienzaniswa negirazi faibha, basalt faibha haina simbi inokuvadza oxides, zvichikonzera kugadzikana kwekemikari zviri nani uye kusimba kwakanyanya munzvimbo dzinoparadza senge alkali yakasimba uye maasidhi akasimba.

Simba rekusimba rebasalt fiber rinowanzobva pa3000 kusvika 4800 MPa, uye elastic modulus yaro iri pakati pe80 kusvika 110 GPa. Izvi zvinoita kuti ive yakasimba kudarika girazi fiber, ine yakaderera elongation panguva yekuzorora, izvo zvinonyatso kuvandudza kutsemuka kwekushomeka kwesimende-yakavakirwa zvinhu.

Basalt fiber inoratidzira yakanakisa-yepamusoro-tembiricha kuramba, ine nzvimbo yekunyungudika inodarika 1400 ° C uye tembiricha yenguva refu yebasa inosvika 700 ° C, inopfuura nekure iyo yegirazi fiber. Izvi zvinobvumira kuchengetedza zvakagadzikana zvinhu zvemuviri kunyange munzvimbo dzepamusoro-tembiricha.

Basalt fiber zvakare ine yepamusoro alkali kuramba, acid resistance, uye UV kuramba. Inogona kuchengetedza hupenyu hurefu hwesevhisi munzvimbo dzakaomarara senge humidity, munyu wekupfapfaidza, uye kemikari corrosion, zvichiita kuti inyatsokodzera zvigadzirwa zveinjiniya senge ekunze madziro plaster layer anooneswa kune yakaoma nharaunda kwenguva yakareba.

2. Crack Resistance Mechanism yeFiber-Reinforced Mortar

Iko kusimbaradza kwefiber mudhaka kunonyanya kuenderana nekugovera kwavo kwenzvimbo, kureba, zvirimo, uye kubatanidza kuita nesimende-yakavakirwa zvinhu. Munguva yekuomeswa kwedhaka, madiki-akatsemuka anogona nyore kuumba mukati nekuda kwezvinhu zvakaita sevhoriyamu shrinkage kubva kune hydration maitiro uye kushushikana kwekupisa kunokonzerwa nekushanduka kwekushisa.

Fibers dzinogona kubhuroka mativi ese e-micro-cracks, ichipa bhiriji mhedzisiro kana makatsemuka atanga kuumbwa, zvinonyatso kunonoka kupararira uye kuvandudza kusimba kwechinyorwa uye kuramba kutsemuka. Basalt fiber ine hutsinye hwepamusoro, iyo inopa yakasimba kupindirana kwemuviri nesamende paste. Kana mitoro yekunze ichiiswa kune dhaka, chikamu chekushushikana chinogona kutamiswa kuburikidza nefibers kune yakapoteredza matrix, nekudaro ichidzikisa kushushikana kwenzvimbo uye kudzivirira kumwe kupararira kwekuputika. Iyi yekudzvinyirira yekuparadzira mashini inobatsira kuvandudza kuoma kwese uye kukanganisa kuramba kwedhaka.

Munguva yekuomesa dhaka, mafiibhi anogona kuumba zvisina tsarukano kugovaniswa Kusimbisa Mesh chimiro mukati me matrix, kuvandudza dhaka deformation kuramba. Kana iyo plaster layer yaiswa kune ekunze tembiricha shanduko, kuomesa shrinkage kushushikana, kana michina mitoro, iyi inosimbisa mesh inogona kunyatso ramba deformation munzvimbo dzekushushikana, zvichitungamira kune yakakwira kuputika kuramba mune izvo zvinhu.
