  A method for replenishing sealant that has escaped from a self-sealing pneumatic tire (2, 10) through one or more holes is disclosed. The self-sealing pneumatic tire comprises a generally toroidal-shaped supporting carcass (4, 14) with an outer circumferential tread (8, 11), two spaced beads (5, 15), at least one ply extending from bead to bead (5, 15), sidewalls (3, 13) extending radially from and connecting said tread (8, 11) to said beads (5, 15), a sealant layer (7, 17) which is disposed radially inwardly from the supporting carcass (4, 14), and an innerliner (6, 16) which is disposed radially inwardly from the sealant layer (7, 17) or between the supporting carcass (4, 14) and the sealant layer (7, 17), and wherein said circumferential tread (8, 11) is adapted to be ground-contacting. In a first aspect, the method comprises injecting a liquid sealant formulation into the sealant layer (7, 17) of the tire (2, 10) through at least one of said holes; and repairing said hole or holes in the supporting carcass (4, 14) and the innerliner (6, 16) of the tire (2, 10). In a second aspect, the method comprises making a slit in the innerliner (6, 16) of the tire (2, 10); injecting a solid sealant composition into the slit to replenish the level of sealant in the tire (2, 10), wherein the sealant composition comprises a butyl rubber and/or polyisobutylene and a peroxide; sealing the slit and any the hole or holes in the supporting carcass (4, 14) of the tire (2, 10); and subjecting the tire (2, 10) to a cure cycle. Also, a sealant composition for repairing self-sealing tires is diclosed consisting or consisting essentially of a liquid polyisobutylene having a weight average molecular weight which is within the range of from 25,000 to 200,000 and a colorant or a pigment.

  本发明公开了一种用于补充通过一个或多个孔从自密封充气轮胎（2，10）中漏出的密封剂的方法。自密封充气轮胎包括一个大体呈环形的支撑胎体（4，14），胎体上有一个外周胎面（8，11）、两个间隔排列的胎圈（5，15）、至少一个从胎圈延伸到胎圈（5，15）的帘布层、从所述胎面（8，11）径向延伸并连接到所述胎圈（5，15）的侧壁（3，13）、密封剂层（7、17），以及内衬（6，16），内衬（6，16）从密封剂层（7，17）径向向内设置，或设置在支撑胎体（4，14）和密封剂层（7，17）之间，其中所述圆周胎面（8，11）适于与地面接触。在第一方面，该方法包括通过至少一个所述孔将液体密封剂配方注入轮胎（2，10）的密封层（7，17）；以及修补轮胎（2，10）的支撑胎体（4，14）和气密层（6，16）上的所述一个或多个孔。第二方面，该方法包括在轮胎（2，10）的气密层（6，16）上开一个缝；将固体密封剂组合物注入缝中，以补充轮胎（2，10）中的密封剂含量，其中密封剂组合物包括丁基橡胶和/或聚异丁烯以及过氧化物；密封缝以及轮胎（2，10）的支撑胎体（4，14）上的一个或多个孔；以及将轮胎（2，10）置于硫化循环中。此外，一种用于修补自密封轮胎的密封剂组合物是由液体聚异丁烯和着色剂或颜料组成或主要由液体聚异丁烯组成，液体聚异丁烯的重量平均分子量在 25,000 至 200,000 之间。

  A pneumatic tire is disclosed comprising a generally toroidal-shaped supporting carcass (4) with an outer circumferential tread (8), two spaced beads (5), at least one ply extending from bead to bead, sidewalls (3) extending radially from and connecting said tread (8) to said beads (5), a sealant layer (7, 17, 27) which is disposed inwardly from the supporting carcass (4), and an innerliner (6, 16, 26) which is disposed inwardly from the sealant layer (7, 17, 27). The sealant layer (7, 17, 27) comprises a sealant composition comprising polyisobutylene or butyl rubber. The polyisobutylene or butyl rubber has a weight average molecular weight which is within the range of from 30,000 to 120,000. Also, a method of manufacturing a pneumatic rubber tire having a puncture sealing feature is disclosed. The method comprises building an unvulcanized tire with said sealant layer (7, 17, 27) wherein the sealant formulation is extruded as said sealant layer (7, 17, 27) onto the unvulcanized supporting carcass (4).

  本发明公开了一种充气轮胎，包括一个大体呈环形的支撑胎体（4），胎体上有一个外周胎面（8）、两个间隔排列的胎圈（5）、至少一个从胎圈延伸到胎圈的帘布层、从所述胎面（8）径向延伸并连接所述胎圈（5）的侧壁（3），从支撑胎体（4）向内设置的密封层（7、17、27），以及从密封层（7、17、27）向内设置的内衬（6、16、26）。密封剂层（7、17、27）包括由聚异丁烯或丁基橡胶组成的密封剂组合物。聚异丁烯或丁基橡胶的重量平均分子量在 30,000 到 120,000 之间。此外，还公开了一种具有穿刺密封功能的充气橡胶轮胎的制造方法。该方法包括制造带有所述密封剂层（7、17、27）的未硫化轮胎，其中密封剂配方作为所述密封剂层（7、17、27）挤出到未硫化的支撑胎体（4）上。

  The present invention relates to an injectable dermal filler composition that can be injected into the skin of the orbital trough of a patient without aggravating darkness around the eyes of the patient. In fact, this composition can be used to lighten such dark areas which have developed over time. The present invention more specifically discloses an injectable dermal filler composition comprising crosslinked hyaluronic acid, a white colorant, and a yellow colorant. The present invention further reveals a method for treating wrinkles and firming an area of skin on a human patient comprising injecting an injectable dermal filler composition comprising crosslinked hyaluronic acid, a white colorant, and a yellow colorant, into the area of skin on the human patient.
