Pob zeb zoo nkauj yog siv rau niaj hnub tsim. Lawv kho ob sab phab ntsa ntawm lub tsev , thiab kho kom zoo nkauj sab hauv cov chav. Imitation lub pob zeb yog ib txoj kev tsim qauv zoo heev thiab yog siv ntau yam qauv thaum dai sab hauv thiab sab nrauv. Thiab koj puas paub hais tias lub pob zeb zoo li no ua rau nws siv cov ntawv tshwj xeeb? Lawv yog cov yas, molded, polyurethane thiab silicone. Txhua yam ntawm cov ntaub ntawv muaj cov nta uas koj yuav tsum xav txog thaum koj yuav. Li ntawd, cia saib seb cov tshuaj pwm li cas yog cov pob zeb zoo nkauj.
Qhov zoo thiab qhov tsis zoo ntawm silicone tuaj pwm rau cov hniav pob zeb
Raws li paub, nyob rau hauv qhuav ntawm cov pob zeb artificial feem ntau siv cov xim pob zeb. Tsis zoo li polyurethane, silicone pwm tsis yog li ntawd resistant rau txhoj puab heev alkaline ib puag ncig ntawm qhob tov, thiab qhov no yog lawv tseem ceeb disadvantage. Cov ntaub ntawv no raug muab rhuav pov tseg kom sai. Gypsum tsis yog li txhoj puab heev ua pob zeb, tab sis thaum nws los ua kev sib txuas nrog silicone, nws muab ib cov nyhuv tsis zoo ntawm cov npuas uas tshwm nyob sab pem hauv ntej ntawm qhov khoom. Thiab qhov thib peb drawback ntawm compound silicone yog nws tsis yog tus nqi tsawg: silicone pwm rau ua zeb pob zeb yog ntau ntau kim tshaj yas.
Raws li rau qhov zoo, lub silicone tseem kub ntev tshaj yas los yas. Tsis tas li ntawd, nws muab cov nyem ntau ntau, qhov no yog qhov tseem ceeb thaum sim ua kom tau ib qho chaw hauv pob zeb nrog kev pab los ntawm silicone pwm. Rau lawv, shrinkage deformations kuj tsis tshwj xeeb, vim cov khoom siv silicone heev mos thiab pliable. Nws yog heev yooj yim uas reusable silicone pwm rau pob zeb vuas cia yooj yim tshem tawm ntawm cov khoom tiav.
Yuav ua li cas ua silicone pwm rau pob zeb?
Cov ntaub ntawv no tuaj yeem ua nrog lawv tus kheej tes. Yog li, cov cuab yeej ntawm lawv cov chaw ua haujlwm yog qhov no:
- Khaws ib lub npov npaj txhij ua pwm (matrix) lossis ua koj tus kheej. Nws yuav tsum tau ua los ntawm cov khoom uas tsis yeem, xws li chipboard, fiberglass, wood boards, thiab lwm yam. Thov nco ntsoov tias yuav tsum tsis txhob muaj qhov khoob ntawm nruab nrab ntawm lub npov ntawm lub thawv, uas los ntawm ib qho tawm ntawm silicone yog ua tau.
- Nyob rau hauv qab ntawm matrix peb nteg sculptural yas (tsis nws tus kheej-hardening, tab sis niaj zaus). Kho nws cov txheej rau kwv yees li ib nrab ntawm lub thawv. Yas yuav tsum zoo compacted, thiaj li hais tias nws nteg ca thiab txawm.
- Los saum toj no rau cov khoom noj khoom haus peb muab cov qauv rau daim ntawv no. Nws tuaj yeem ua tau ib lub pob zeb ntawm cov duab los yog ib lub pobzeb npaj rau hauv pob zeb.
- Kom tsis txhob hloov cov duab, nws yog ntshaw kom ntau qhov nyob rau hauv av nplaum nyob rau hauv lub neej yav tom ntej - xauv.
- Tam sim no peb xam ntau npaum li cas tsim khoom siv. Ua li no, nqa tej khoom siv, hnoos nws rau hauv pwm, thiab nchuav nws rov qab rau hauv lub khob ntsuas thiab ntsuas qhov ntim.
- Tom qab ntawd lub matrix yuav tsum tau kho nrog ib tug separator. Nws tuaj yeem ua xabnpas
tov, roj, ciab los yog kev sib cais tshwj xeeb. Tsis txhob siv cov roj nplua nyeem raws li silicone. - Sib tov cov khoom xyaw ntawm moulding raws li qhia nyob rau hauv cov lus qhia, thiab hliv lub silicone rau hauv matrix. Qhov no yuav tsum tau ua kom zoo, nyob rau hauv ib qho trickle, pib nrog cov duab contour los tiv thaiv tus tsim ntawm npuas.
- Thaum lub sab qaum ua tiav lawm, cov yas yuav tsum ua tib zoo muab tshem tawm, qhov nto thiab qauv yuav tsum tau smeared nrog lub separator thiab tom qab ntawd ces nchuav nrog ob tog tiv thaiv pwm silicone.
- Ib hnub tom qab daim ntawv sib cais, thiab cov qauv yog muab rho tawm los ntawm daim ntawv teev. Nws npaj txhij siv!
