Of switch of window of aluminium alloy door defend

In our daily life, the regular meeting of aluminium alloy classics in the home encounters a few problems, let us discuss together fall how to solve these problems:

One, if appear,open the window that close the door from time to tome block sluggish phenomenon, switch needs very great strength, casing fan is built receive width small, circumjacent crack is not fair when the phenomenon, cause by the following elements commonly:
(1) door window frame or fan are out of shape, sealing strip becomes loose fall off.
(2) hardware fittings damages.
(3) installs quality difference, exceed tolerance very much, did not grant to be adjusted in time again.
Measure of prevention and cure:
(Installation of 1) door window should accord with installation working procedure, be checked at any time and adjust the installation quality of every working procedure.
(2) window frame and an opening in a wall all want lay off central line, central line wants to be opposite when window frame loads mouth of a cave neat, casing horn is made secure temporarily, the verticality that adjusts window frame carefully, level is spent reach straight angle, the error should be inside tolerance limits.
(Diagonal and flatness deviation should be checked before 3) door casement joins draw a frame round, after joining draw a frame round, want to use what feet of board feet, a place of strategic importance checks casing fan to build accept width, circumjacent crack, till accord with a requirement.
(4) installs hardware part correctly, discover attaint should change in time.
(5) does protection of good finished product to reach at ordinary times use maintain, avoid outside force impact, do not get pensile heavy thing, cause door window to be out of shape. When using, want to leave gently to close gently, prolong its service life.
2, the reason that fittings of hardware of plastic door window damages and measure of prevention and cure
Fittings of hardware of plastic door window damages average performance is: Hardware fittings is fixed not firm, become loose fall off, pulley, slippery maintain the attaint such as hinge, open shut not agile.
Cause hardware the reason of attaint: Hardware fittings choice is undeserved, when inferior; originallies closely, quality did not set metallic scaleboard, without enough installation strength.
Hardware of prevention and cure the measure of attaint:
(The model that 1) chooses hardware fittings, norms and function should accord with a country active standard and concerned regulation, match with look of chosen plastic door window.
(2) exceeds the push-pull window of 1m to width, or the door window that installs double deck glass, should choose double pulley, or choose scroll pulley.
(3) is slippery maintain hinge to must not use aluminium alloy data, should use stainless steel data
(4) installs hardware with close solid screw, must inside set metallic scaleboard, double what scaleboard ply should be more than fastener tooth to be apart from at least. Do not get close solid to be on plastic profile, also must not use metalloid liner.
(5) hardware fittings should be installed finally, should assemble door window lock, shake handshandle again after window door leaf joins draw a frame round, make sure the place is proper, switch is quick.
(6) hardware should notice to maintain after installation, prevent to rust corrode. Want to leave gently to close gently in be used daily, prevent to leave forcedly to close forcedly, cause damage.
